 131  *           PROCESS_CallUserSignalProc
 132  *
 133  * FIXME:  Some of the signals aren't sent correctly!
 134  *
 135  * The exact meaning of the USER signals is undocumented, but this
 136  * should cover the basic idea:
 137  *
 138  * USIG_DLL_UNLOAD_WIN16
 139  *     This is sent when a 16-bit module is unloaded.
 140  *
 141  * USIG_DLL_UNLOAD_WIN32
 142  *     This is sent when a 32-bit module is unloaded.
 143  *
 144  * USIG_DLL_UNLOAD_ORPHANS
 145  *     This is sent after the last Win3.1 module is unloaded,
 146  *     to allow removal of orphaned menus.
 147  *
 148  * USIG_FAULT_DIALOG_PUSH
 149  * USIG_FAULT_DIALOG_POP
 150  *     These are called to allow USER to prepare for displaying a
 151  *     fault dialog, even though the fault might have happened while
 152  *     inside a USER critical section.
 153  *
 154  * USIG_THREAD_INIT
 155  *     This is called from the context of a new thread, as soon as it
 156  *     has started to run.
 157  *
 158  * USIG_THREAD_EXIT
 159  *     This is called, still in its context, just before a thread is
 160  *     about to terminate.
 161  *
 162  * USIG_PROCESS_CREATE
 163  *     This is called, in the parent process context, after a new process
 164  *     has been created.
 165  *
 166  * USIG_PROCESS_INIT
 167  *     This is called in the new process context, just after the main thread
 168  *     has started execution (after the main thread's USIG_THREAD_INIT has
 169  *     been sent).
 170  *
 171  * USIG_PROCESS_LOADED
 172  *     This is called after the executable file has been loaded into the
 173  *     new process context.
 174  *
 175  * USIG_PROCESS_RUNNING
 176  *     This is called immediately before the main entry point is called.
 177  *
 178  * USIG_PROCESS_EXIT
 179  *     This is called in the context of a process that is about to
 180  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 181  *     been sent).
 182  *
 183  * USIG_PROCESS_DESTROY
 184  *     This is called after a process has terminated.
 185  *
 186  *
 187  * The meaning of the dwFlags bits is as follows:
 188  *
 189  * USIG_FLAGS_WIN32
 190  *     Current process is 32-bit.
 191  *
 192  * USIG_FLAGS_GUI
 193  *     Current process is a (Win32) GUI process.
 194  *
 195  * USIG_FLAGS_FEEDBACK
 196  *     Current process needs 'feedback' (determined from the STARTUPINFO
 197  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 198  *
 199  * USIG_FLAGS_FAULT
 200  *     The signal is being sent due to a fault.
