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