 110  *           PROCESS_CallUserSignalProc
 111  *
 112  * FIXME:  Some of the signals aren't sent correctly!
 113  *
 114  * The exact meaning of the USER signals is undocumented, but this
 115  * should cover the basic idea:
 116  *
 117  * USIG_DLL_UNLOAD_WIN16
 118  *     This is sent when a 16-bit module is unloaded.
 119  *
 120  * USIG_DLL_UNLOAD_WIN32
 121  *     This is sent when a 32-bit module is unloaded.
 122  *
 123  * USIG_DLL_UNLOAD_ORPHANS
 124  *     This is sent after the last Win3.1 module is unloaded,
 125  *     to allow removal of orphaned menus.
 126  *
 127  * USIG_FAULT_DIALOG_PUSH
 128  * USIG_FAULT_DIALOG_POP
 129  *     These are called to allow USER to prepare for displaying a
 130  *     fault dialog, even though the fault might have happened while
 131  *     inside a USER critical section.
 132  *
 133  * USIG_THREAD_INIT
 134  *     This is called from the context of a new thread, as soon as it
 135  *     has started to run.
 136  *
 137  * USIG_THREAD_EXIT
 138  *     This is called, still in its context, just before a thread is
 139  *     about to terminate.
 140  *
 141  * USIG_PROCESS_CREATE
 142  *     This is called, in the parent process context, after a new process
 143  *     has been created.
 144  *
 145  * USIG_PROCESS_INIT
 146  *     This is called in the new process context, just after the main thread
 147  *     has started execution (after the main thread's USIG_THREAD_INIT has
 148  *     been sent).
 149  *
 150  * USIG_PROCESS_LOADED
 151  *     This is called after the executable file has been loaded into the
 152  *     new process context.
 153  *
 154  * USIG_PROCESS_RUNNING
 155  *     This is called immediately before the main entry point is called.
 156  *
 157  * USIG_PROCESS_EXIT
 158  *     This is called in the context of a process that is about to
 159  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 160  *     been sent).
 161  *
 162  * USIG_PROCESS_DESTROY
 163  *     This is called after a process has terminated.
 164  *
 165  *
 166  * The meaning of the dwFlags bits is as follows:
 167  *
 168  * USIG_FLAGS_WIN32
 169  *     Current process is 32-bit.
 170  *
 171  * USIG_FLAGS_GUI
 172  *     Current process is a (Win32) GUI process.
 173  *
 174  * USIG_FLAGS_FEEDBACK
 175  *     Current process needs 'feedback' (determined from the STARTUPINFO
 176  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 177  *
 178  * USIG_FLAGS_FAULT
 179  *     The signal is being sent due to a fault.
