  47  *           PROCESS_CallUserSignalProc
  48  *
  49  * FIXME:  Some of the signals aren't sent correctly!
  50  *
  51  * The exact meaning of the USER signals is undocumented, but this
  52  * should cover the basic idea:
  53  *
  54  * USIG_DLL_UNLOAD_WIN16
  55  *     This is sent when a 16-bit module is unloaded.
  56  *
  57  * USIG_DLL_UNLOAD_WIN32
  58  *     This is sent when a 32-bit module is unloaded.
  59  *
  60  * USIG_DLL_UNLOAD_ORPHANS
  61  *     This is sent after the last Win3.1 module is unloaded,
  62  *     to allow removal of orphaned menus.
  63  *
  64  * USIG_FAULT_DIALOG_PUSH
  65  * USIG_FAULT_DIALOG_POP
  66  *     These are called to allow USER to prepare for displaying a
  67  *     fault dialog, even though the fault might have happened while
  68  *     inside a USER critical section.
  69  *
  70  * USIG_THREAD_INIT
  71  *     This is called from the context of a new thread, as soon as it
  72  *     has started to run.
  73  *
  74  * USIG_THREAD_EXIT
  75  *     This is called, still in its context, just before a thread is
  76  *     about to terminate.
  77  *
  78  * USIG_PROCESS_CREATE
  79  *     This is called, in the parent process context, after a new process
  80  *     has been created.
  81  *
  82  * USIG_PROCESS_INIT
  83  *     This is called in the new process context, just after the main thread
  84  *     has started execution (after the main thread's USIG_THREAD_INIT has
  85  *     been sent).
  86  *
  87  * USIG_PROCESS_LOADED
  88  *     This is called after the executable file has been loaded into the
  89  *     new process context.
  90  *
  91  * USIG_PROCESS_RUNNING
  92  *     This is called immediately before the main entry point is called.
  93  *
  94  * USIG_PROCESS_EXIT
  95  *     This is called in the context of a process that is about to
  96  *     terminate (but before the last thread's USIG_THREAD_EXIT has
  97  *     been sent).
  98  *
  99  * USIG_PROCESS_DESTROY
 100  *     This is called after a process has terminated.
 101  *
 102  *
 103  * The meaning of the dwFlags bits is as follows:
 104  *
 105  * USIG_FLAGS_WIN32
 106  *     Current process is 32-bit.
 107  *
 108  * USIG_FLAGS_GUI
 109  *     Current process is a (Win32) GUI process.
 110  *
 111  * USIG_FLAGS_FEEDBACK
 112  *     Current process needs 'feedback' (determined from the STARTUPINFO
 113  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 114  *
 115  * USIG_FLAGS_FAULT
 116  *     The signal is being sent due to a fault.
