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