+// The attach mechanism on Solaris is implemented using the Doors IPC
+// mechanism. The first tool to attempt to attach causes the attach
+// listener thread to startup. This thread creats a door that is
+// associated with a function that enqueues an operation to the attach
+// listener. The door is attached to a file in the file system so that
+// client (tools) can locate it. To enqueue an operation to the VM the
+// client calls through the door which invokes the enqueue function in
+// this process. The credentials of the client are checked and if the
+// effective uid matches this process then the operation is enqueued.
+// When an operation completes the attach listener is required to send the
+// operation result and any result data to the client. In this implementation
+// the result is returned via a UNIX domain socket. A pair of connected
+// sockets (socketpair) is created in the enqueue function and the file
+// descriptor for one of the sockets is returned to the client as the
+// return from the door call. The other end is retained in this process.
+// When the operation completes the result is sent to the client and
+// the socket is closed.

+//       so Java priorities are mapped to libthread priorities and we map from
+//       the latter to lwp priorities.  We don't keep priorities stored in

+// We implement Solaris and Linux PlatformEvents with the
+// obvious condvar-mutex-flag triple.
+// Another alternative that works quite well is pipes:
+// Each PlatformEvent consists of a pipe-pair.
+// The thread associated with the PlatformEvent
+// calls park(), which reads from the input end of the pipe.
+// Unpark() writes into the other end of the pipe.
+// The write-side of the pipe must be set NDELAY.
+// Unfortunately pipes consume a large # of handles.
+// Native solaris lwp_park() and lwp_unpark() work nicely, too.
+// Using pipes for the 1st few threads might be workable, however.
+//
+// park() is permitted to return spuriously.
+// Callers of park() should wrap the call to park() in
+// an appropriate loop.  A litmus test for the correct
+// usage of park is the following: if park() were modified
+// to immediately return 0 your code should still work,
+// albeit degenerating to a spin loop.
+//
+// In a sense, park()-unpark() just provides more polite spinning
+// and polling with the key difference over naive spinning being
+// that a parked thread needs to be explicitly unparked() in order
+// to wake up and to poll the underlying condition.
+//
+// Assumption:
+//    Only one parker can exist on an event, which is why we allocate
+//    them per-thread. Multiple unparkers can coexist.
+//
+// _event transitions in park()
+//   -1 => -1 : illegal
+//    1 =>  0 : pass - return immediately
+//    0 => -1 : block; then set _event to 0 before returning
+//
+// _event transitions in unpark()
+//    0 => 1 : just return
+//    1 => 1 : just return
+//   -1 => either 0 or 1; must signal target thread
+//         That is, we can safely transition _event from -1 to either
+//         0 or 1.
+//
+// _event serves as a restricted-range semaphore.
+//   -1 : thread is blocked, i.e. there is a waiter
+//    0 : neutral: thread is running or ready,
+//        could have been signaled after a wait started
+//    1 : signaled - thread is running or ready
+//
+// Another possible encoding of _event would be with
+// explicit "PARKED" == 01b and "SIGNALED" == 10b bits.
+//
+// TODO-FIXME: add DTRACE probes for:
+// 1.   Tx parks
+// 2.   Ty unparks Tx
+// 3.   Tx resumes from park
+

+// -------------------------------------------------------
+
+// The solaris and linux implementations of park/unpark are fairly
+// conservative for now, but can be improved. They currently use a
+// mutex/condvar pair, plus _counter.
+// Park decrements _counter if > 0, else does a condvar wait.  Unpark
+// sets count to 1 and signals condvar.  Only one thread ever waits
+// on the condvar. Contention seen when trying to park implies that someone
+// is unparking you, so don't wait. And spurious returns are fine, so there

+// 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures
+// When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in
+// system header files.  On 32-bit architectures, there is no problem.
+// On 64-bit architectures, defining NULL as a 32-bit constant can cause
+// problems with varargs functions: C++ integral promotion rules say for
+// varargs, we pass the argument 0 as an int.  So, if NULL was passed to a
+// varargs function it will remain 32-bits.  Depending on the calling
+// convention of the machine, if the argument is passed on the stack then
+// only 32-bits of the "NULL" pointer may be initialized to zero.  The
+// other 32-bits will be garbage.  If the varargs function is expecting a
+// pointer when it extracts the argument, then we have a problem.
+//
+// Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0.
+//
+// Note: this fix doesn't work well on Linux because NULL will be overwritten
