  76  *              SignalProc32 (USER.391)
  77  *              UserSignalProc (USER32.@)
  78  *
  79  * The exact meaning of the USER signals is undocumented, but this
  80  * should cover the basic idea:
  81  *
  82  * USIG_DLL_UNLOAD_WIN16
  83  *     This is sent when a 16-bit module is unloaded.
  84  *
  85  * USIG_DLL_UNLOAD_WIN32
  86  *     This is sent when a 32-bit module is unloaded.
  87  *
  88  * USIG_DLL_UNLOAD_ORPHANS
  89  *     This is sent after the last Win3.1 module is unloaded,
  90  *     to allow removal of orphaned menus.
  91  *
  92  * USIG_FAULT_DIALOG_PUSH
  93  * USIG_FAULT_DIALOG_POP
  94  *     These are called to allow USER to prepare for displaying a
  95  *     fault dialog, even though the fault might have happened while
  96  *     inside a USER critical section.
  97  *
  98  * USIG_THREAD_INIT
  99  *     This is called from the context of a new thread, as soon as it
 100  *     has started to run.
 101  *
 102  * USIG_THREAD_EXIT
 103  *     This is called, still in its context, just before a thread is
 104  *     about to terminate.
 105  *
 106  * USIG_PROCESS_CREATE
 107  *     This is called, in the parent process context, after a new process
 108  *     has been created.
 109  *
 110  * USIG_PROCESS_INIT
 111  *     This is called in the new process context, just after the main thread
 112  *     has started execution (after the main thread's USIG_THREAD_INIT has
 113  *     been sent).
 114  *
 115  * USIG_PROCESS_LOADED
 116  *     This is called after the executable file has been loaded into the
 117  *     new process context.
 118  *
 119  * USIG_PROCESS_RUNNING
 120  *     This is called immediately before the main entry point is called.
 121  *
 122  * USIG_PROCESS_EXIT
 123  *     This is called in the context of a process that is about to
 124  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 125  *     been sent).
 126  *
 127  * USIG_PROCESS_DESTROY
 128  *     This is called after a process has terminated.
 129  *
 130  *
 131  * The meaning of the dwFlags bits is as follows:
 132  *
 133  * USIG_FLAGS_WIN32
 134  *     Current process is 32-bit.
 135  *
 136  * USIG_FLAGS_GUI
 137  *     Current process is a (Win32) GUI process.
 138  *
 139  * USIG_FLAGS_FEEDBACK
 140  *     Current process needs 'feedback' (determined from the STARTUPINFO
 141  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 142  *
 143  * USIG_FLAGS_FAULT
 144  *     The signal is being sent due to a fault.
