 200  *
 201  * The exact meaning of the USER signals is undocumented, but this
 202  * should cover the basic idea:
 203  *
 204  * USIG_DLL_UNLOAD_WIN16
 205  *     This is sent when a 16-bit module is unloaded.
 206  *
 207  * USIG_DLL_UNLOAD_WIN32
 208  *     This is sent when a 32-bit module is unloaded.
 209  *
 210  * USIG_DLL_UNLOAD_ORPHANS
 211  *     This is sent after the last Win3.1 module is unloaded,
 212  *     to allow removal of orphaned menus.
 213  *
 214  * USIG_FAULT_DIALOG_PUSH
 215  * USIG_FAULT_DIALOG_POP
 216  *     These are called to allow USER to prepare for displaying a
 217  *     fault dialog, even though the fault might have happened while
 218  *     inside a USER critical section.
 219  *
 220  * USIG_THREAD_INIT
 221  *     This is called from the context of a new thread, as soon as it
 222  *     has started to run.
 223  *
 224  * USIG_THREAD_EXIT
 225  *     This is called, still in its context, just before a thread is
 226  *     about to terminate.
 227  *
 228  * USIG_PROCESS_CREATE
 229  *     This is called, in the parent process context, after a new process
 230  *     has been created.
 231  *
 232  * USIG_PROCESS_INIT
 233  *     This is called in the new process context, just after the main thread
 234  *     has started execution (after the main thread's USIG_THREAD_INIT has
 235  *     been sent).
 236  *
 237  * USIG_PROCESS_LOADED
 238  *     This is called after the executable file has been loaded into the
 239  *     new process context.
 240  *
 241  * USIG_PROCESS_RUNNING
 242  *     This is called immediately before the main entry point is called.
 243  *
 244  * USIG_PROCESS_EXIT
 245  *     This is called in the context of a process that is about to
 246  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 247  *     been sent).
 248  *
 249  * USIG_PROCESS_DESTROY
 250  *     This is called after a process has terminated.
 251  *
 252  *
 253  * The meaning of the dwFlags bits is as follows:
 254  *
 255  * USIG_FLAGS_WIN32
 256  *     Current process is 32-bit.
 257  *
 258  * USIG_FLAGS_GUI
 259  *     Current process is a (Win32) GUI process.
 260  *
 261  * USIG_FLAGS_FEEDBACK
 262  *     Current process needs 'feedback' (determined from the STARTUPINFO
 263  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 264  *
 265  * USIG_FLAGS_FAULT
 266  *     The signal is being sent due to a fault.
