  61  *
  62  * FIXME:  Some of the signals aren't sent correctly!
  63  *
  64  * The exact meaning of the USER signals is undocumented, but this
  65  * should cover the basic idea:
  66  *
  67  * USIG_DLL_UNLOAD_WIN16
  68  *     This is sent when a 16-bit module is unloaded.
  69  *
  70  * USIG_DLL_UNLOAD_WIN32
  71  *     This is sent when a 32-bit module is unloaded.
  72  *
  73  * USIG_DLL_UNLOAD_ORPHANS
  74  *     This is sent after the last Win3.1 module is unloaded,
  75  *     to allow removal of orphaned menus.
  76  *
  77  * USIG_FAULT_DIALOG_PUSH
  78  * USIG_FAULT_DIALOG_POP
  79  *     These are called to allow USER to prepare for displaying a
  80  *     fault dialog, even though the fault might have happened while
  81  *     inside a USER critical section.
  82  *
  83  * USIG_THREAD_INIT
  84  *     This is called from the context of a new thread, as soon as it
  85  *     has started to run.
  86  *
  87  * USIG_THREAD_EXIT
  88  *     This is called, still in its context, just before a thread is
  89  *     about to terminate.
  90  *
  91  * USIG_PROCESS_CREATE
  92  *     This is called, in the parent process context, after a new process
  93  *     has been created.
  94  *
  95  * USIG_PROCESS_INIT
  96  *     This is called in the new process context, just after the main thread
  97  *     has started execution (after the main thread's USIG_THREAD_INIT has
  98  *     been sent).
  99  *
 100  * USIG_PROCESS_LOADED
 101  *     This is called after the executable file has been loaded into the
 102  *     new process context.
 103  *
 104  * USIG_PROCESS_RUNNING
 105  *     This is called immediately before the main entry point is called.
 106  *
 107  * USIG_PROCESS_EXIT
 108  *     This is called in the context of a process that is about to
 109  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 110  *     been sent).
 111  *
 112  * USIG_PROCESS_DESTROY
 113  *     This is called after a process has terminated.
 114  *
 115  *
 116  * The meaning of the dwFlags bits is as follows:
 117  *
 118  * USIG_FLAGS_WIN32
 119  *     Current process is 32-bit.
 120  *
 121  * USIG_FLAGS_GUI
 122  *     Current process is a (Win32) GUI process.
 123  *
 124  * USIG_FLAGS_FEEDBACK
 125  *     Current process needs 'feedback' (determined from the STARTUPINFO
 126  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 127  *
 128  * USIG_FLAGS_FAULT
 129  *     The signal is being sent due to a fault.
