 112  *           PROCESS_CallUserSignalProc
 113  *
 114  * FIXME:  Some of the signals aren't sent correctly!
 115  *
 116  * The exact meaning of the USER signals is undocumented, but this
 117  * should cover the basic idea:
 118  *
 119  * USIG_DLL_UNLOAD_WIN16
 120  *     This is sent when a 16-bit module is unloaded.
 121  *
 122  * USIG_DLL_UNLOAD_WIN32
 123  *     This is sent when a 32-bit module is unloaded.
 124  *
 125  * USIG_DLL_UNLOAD_ORPHANS
 126  *     This is sent after the last Win3.1 module is unloaded,
 127  *     to allow removal of orphaned menus.
 128  *
 129  * USIG_FAULT_DIALOG_PUSH
 130  * USIG_FAULT_DIALOG_POP
 131  *     These are called to allow USER to prepare for displaying a
 132  *     fault dialog, even though the fault might have happened while
 133  *     inside a USER critical section.
 134  *
 135  * USIG_THREAD_INIT
 136  *     This is called from the context of a new thread, as soon as it
 137  *     has started to run.
 138  *
 139  * USIG_THREAD_EXIT
 140  *     This is called, still in its context, just before a thread is
 141  *     about to terminate.
 142  *
 143  * USIG_PROCESS_CREATE
 144  *     This is called, in the parent process context, after a new process
 145  *     has been created.
 146  *
 147  * USIG_PROCESS_INIT
 148  *     This is called in the new process context, just after the main thread
 149  *     has started execution (after the main thread's USIG_THREAD_INIT has
 150  *     been sent).
 151  *
 152  * USIG_PROCESS_LOADED
 153  *     This is called after the executable file has been loaded into the
 154  *     new process context.
 155  *
 156  * USIG_PROCESS_RUNNING
 157  *     This is called immediately before the main entry point is called.
 158  *
 159  * USIG_PROCESS_EXIT
 160  *     This is called in the context of a process that is about to
 161  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 162  *     been sent).
 163  *
 164  * USIG_PROCESS_DESTROY
 165  *     This is called after a process has terminated.
 166  *
 167  *
 168  * The meaning of the dwFlags bits is as follows:
 169  *
 170  * USIG_FLAGS_WIN32
 171  *     Current process is 32-bit.
 172  *
 173  * USIG_FLAGS_GUI
 174  *     Current process is a (Win32) GUI process.
 175  *
 176  * USIG_FLAGS_FEEDBACK
 177  *     Current process needs 'feedback' (determined from the STARTUPINFO
 178  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 179  *
 180  * USIG_FLAGS_FAULT
 181  *     The signal is being sent due to a fault.
