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