  71  * FIXME:  Some of the signals aren't sent correctly!
  72  *
  73  * The exact meaning of the USER signals is undocumented, but this
  74  * should cover the basic idea:
  75  *
  76  * USIG_DLL_UNLOAD_WIN16
  77  *     This is sent when a 16-bit module is unloaded.
  78  *
  79  * USIG_DLL_UNLOAD_WIN32
  80  *     This is sent when a 32-bit module is unloaded.
  81  *
  82  * USIG_DLL_UNLOAD_ORPHANS
  83  *     This is sent after the last Win3.1 module is unloaded,
  84  *     to allow removal of orphaned menus.
  85  *
  86  * USIG_FAULT_DIALOG_PUSH
  87  * USIG_FAULT_DIALOG_POP
  88  *     These are called to allow USER to prepare for displaying a
  89  *     fault dialog, even though the fault might have happened while
  90  *     inside a USER critical section.
  91  *
  92  * USIG_THREAD_INIT
  93  *     This is called from the context of a new thread, as soon as it
  94  *     has started to run.
  95  *
  96  * USIG_THREAD_EXIT
  97  *     This is called, still in its context, just before a thread is
  98  *     about to terminate.
  99  *
 100  * USIG_PROCESS_CREATE
 101  *     This is called, in the parent process context, after a new process
 102  *     has been created.
 103  *
 104  * USIG_PROCESS_INIT
 105  *     This is called in the new process context, just after the main thread
 106  *     has started execution (after the main thread's USIG_THREAD_INIT has
 107  *     been sent).
 108  *
 109  * USIG_PROCESS_LOADED
 110  *     This is called after the executable file has been loaded into the
 111  *     new process context.
 112  *
 113  * USIG_PROCESS_RUNNING
 114  *     This is called immediately before the main entry point is called.
 115  *
 116  * USIG_PROCESS_EXIT
 117  *     This is called in the context of a process that is about to
 118  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 119  *     been sent).
 120  *
 121  * USIG_PROCESS_DESTROY
 122  *     This is called after a process has terminated.
 123  *
 124  *
 125  * The meaning of the dwFlags bits is as follows:
 126  *
 127  * USIG_FLAGS_WIN32
 128  *     Current process is 32-bit.
 129  *
 130  * USIG_FLAGS_GUI
 131  *     Current process is a (Win32) GUI process.
 132  *
 133  * USIG_FLAGS_FEEDBACK
 134  *     Current process needs 'feedback' (determined from the STARTUPINFO
 135  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 136  *
 137  * USIG_FLAGS_FAULT
 138  *     The signal is being sent due to a fault.
