* PROCESS_CallUserSignalProc

* FIXME: Some of the signals aren't sent correctly!
*
* The exact meaning of the USER signals is undocumented, but this
* should cover the basic idea:
*
* USIG_DLL_UNLOAD_WIN16
* This is sent when a 16-bit module is unloaded.
*
* USIG_DLL_UNLOAD_WIN32
* This is sent when a 32-bit module is unloaded.
*
* USIG_DLL_UNLOAD_ORPHANS
* This is sent after the last Win3.1 module is unloaded,
* to allow removal of orphaned menus.
*
* USIG_FAULT_DIALOG_PUSH
* USIG_FAULT_DIALOG_POP
* These are called to allow USER to prepare for displaying a
* fault dialog, even though the fault might have happened while
* inside a USER critical section.
*
* USIG_THREAD_INIT
* This is called from the context of a new thread, as soon as it
* has started to run.
*
* USIG_THREAD_EXIT
* This is called, still in its context, just before a thread is
* about to terminate.
*
* USIG_PROCESS_CREATE
* This is called, in the parent process context, after a new process
* has been created.
*
* USIG_PROCESS_INIT
* This is called in the new process context, just after the main thread
* has started execution (after the main thread's USIG_THREAD_INIT has
* been sent).
*
* USIG_PROCESS_LOADED
* This is called after the executable file has been loaded into the
* new process context.
*
* USIG_PROCESS_RUNNING
* This is called immediately before the main entry point is called.
*
* USIG_PROCESS_EXIT
* This is called in the context of a process that is about to
* terminate (but before the last thread's USIG_THREAD_EXIT has
* been sent).
*
* USIG_PROCESS_DESTROY
* This is called after a process has terminated.
*
*
* The meaning of the dwFlags bits is as follows:
*
* USIG_FLAGS_WIN32
* Current process is 32-bit.
*
* USIG_FLAGS_GUI
* Current process is a (Win32) GUI process.
*
* USIG_FLAGS_FEEDBACK
* Current process needs 'feedback' (determined from the STARTUPINFO
* flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
*
* USIG_FLAGS_FAULT
* The signal is being sent due to a fault.
