 143  *           PROCESS_CallUserSignalProc
 144  *
 145  * FIXME:  Some of the signals aren't sent correctly!
 146  *
 147  * The exact meaning of the USER signals is undocumented, but this
 148  * should cover the basic idea:
 149  *
 150  * USIG_DLL_UNLOAD_WIN16
 151  *     This is sent when a 16-bit module is unloaded.
 152  *
 153  * USIG_DLL_UNLOAD_WIN32
 154  *     This is sent when a 32-bit module is unloaded.
 155  *
 156  * USIG_DLL_UNLOAD_ORPHANS
 157  *     This is sent after the last Win3.1 module is unloaded,
 158  *     to allow removal of orphaned menus.
 159  *
 160  * USIG_FAULT_DIALOG_PUSH
 161  * USIG_FAULT_DIALOG_POP
 162  *     These are called to allow USER to prepare for displaying a
 163  *     fault dialog, even though the fault might have happened while
 164  *     inside a USER critical section.
 165  *
 166  * USIG_THREAD_INIT
 167  *     This is called from the context of a new thread, as soon as it
 168  *     has started to run.
 169  *
 170  * USIG_THREAD_EXIT
 171  *     This is called, still in its context, just before a thread is
 172  *     about to terminate.
 173  *
 174  * USIG_PROCESS_CREATE
 175  *     This is called, in the parent process context, after a new process
 176  *     has been created.
 177  *
 178  * USIG_PROCESS_INIT
 179  *     This is called in the new process context, just after the main thread
 180  *     has started execution (after the main thread's USIG_THREAD_INIT has
 181  *     been sent).
 182  *
 183  * USIG_PROCESS_LOADED
 184  *     This is called after the executable file has been loaded into the
 185  *     new process context.
 186  *
 187  * USIG_PROCESS_RUNNING
 188  *     This is called immediately before the main entry point is called.
 189  *
 190  * USIG_PROCESS_EXIT
 191  *     This is called in the context of a process that is about to
 192  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 193  *     been sent).
 194  *
 195  * USIG_PROCESS_DESTROY
 196  *     This is called after a process has terminated.
 197  *
 198  *
 199  * The meaning of the dwFlags bits is as follows:
 200  *
 201  * USIG_FLAGS_WIN32
 202  *     Current process is 32-bit.
 203  *
 204  * USIG_FLAGS_GUI
 205  *     Current process is a (Win32) GUI process.
 206  *
 207  * USIG_FLAGS_FEEDBACK
 208  *     Current process needs 'feedback' (determined from the STARTUPINFO
 209  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 210  *
 211  * USIG_FLAGS_FAULT
 212  *     The signal is being sent due to a fault.
