 118  * FIXME:  Some of the signals aren't sent correctly!
 119  *
 120  * The exact meaning of the USER signals is undocumented, but this
 121  * should cover the basic idea:
 122  *
 123  * USIG_DLL_UNLOAD_WIN16
 124  *     This is sent when a 16-bit module is unloaded.
 125  *
 126  * USIG_DLL_UNLOAD_WIN32
 127  *     This is sent when a 32-bit module is unloaded.
 128  *
 129  * USIG_DLL_UNLOAD_ORPHANS
 130  *     This is sent after the last Win3.1 module is unloaded,
 131  *     to allow removal of orphaned menus.
 132  *
 133  * USIG_FAULT_DIALOG_PUSH
 134  * USIG_FAULT_DIALOG_POP
 135  *     These are called to allow USER to prepare for displaying a
 136  *     fault dialog, even though the fault might have happened while
 137  *     inside a USER critical section.
 138  *
 139  * USIG_THREAD_INIT
 140  *     This is called from the context of a new thread, as soon as it
 141  *     has started to run.
 142  *
 143  * USIG_THREAD_EXIT
 144  *     This is called, still in its context, just before a thread is
 145  *     about to terminate.
 146  *
 147  * USIG_PROCESS_CREATE
 148  *     This is called, in the parent process context, after a new process
 149  *     has been created.
 150  *
 151  * USIG_PROCESS_INIT
 152  *     This is called in the new process context, just after the main thread
 153  *     has started execution (after the main thread's USIG_THREAD_INIT has
 154  *     been sent).
 155  *
 156  * USIG_PROCESS_LOADED
 157  *     This is called after the executable file has been loaded into the
 158  *     new process context.
 159  *
 160  * USIG_PROCESS_RUNNING
 161  *     This is called immediately before the main entry point is called.
 162  *
 163  * USIG_PROCESS_EXIT
 164  *     This is called in the context of a process that is about to
 165  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 166  *     been sent).
 167  *
 168  * USIG_PROCESS_DESTROY
 169  *     This is called after a process has terminated.
 170  *
 171  *
 172  * The meaning of the dwFlags bits is as follows:
 173  *
 174  * USIG_FLAGS_WIN32
 175  *     Current process is 32-bit.
 176  *
 177  * USIG_FLAGS_GUI
 178  *     Current process is a (Win32) GUI process.
 179  *
 180  * USIG_FLAGS_FEEDBACK
 181  *     Current process needs 'feedback' (determined from the STARTUPINFO
 182  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 183  *
 184  * USIG_FLAGS_FAULT
 185  *     The signal is being sent due to a fault.
