 113  *           PROCESS_CallUserSignalProc
 114  *
 115  * FIXME:  Some of the signals aren't sent correctly!
 116  *
 117  * The exact meaning of the USER signals is undocumented, but this
 118  * should cover the basic idea:
 119  *
 120  * USIG_DLL_UNLOAD_WIN16
 121  *     This is sent when a 16-bit module is unloaded.
 122  *
 123  * USIG_DLL_UNLOAD_WIN32
 124  *     This is sent when a 32-bit module is unloaded.
 125  *
 126  * USIG_DLL_UNLOAD_ORPHANS
 127  *     This is sent after the last Win3.1 module is unloaded,
 128  *     to allow removal of orphaned menus.
 129  *
 130  * USIG_FAULT_DIALOG_PUSH
 131  * USIG_FAULT_DIALOG_POP
 132  *     These are called to allow USER to prepare for displaying a
 133  *     fault dialog, even though the fault might have happened while
 134  *     inside a USER critical section.
 135  *
 136  * USIG_THREAD_INIT
 137  *     This is called from the context of a new thread, as soon as it
 138  *     has started to run.
 139  *
 140  * USIG_THREAD_EXIT
 141  *     This is called, still in its context, just before a thread is
 142  *     about to terminate.
 143  *
 144  * USIG_PROCESS_CREATE
 145  *     This is called, in the parent process context, after a new process
 146  *     has been created.
 147  *
 148  * USIG_PROCESS_INIT
 149  *     This is called in the new process context, just after the main thread
 150  *     has started execution (after the main thread's USIG_THREAD_INIT has
 151  *     been sent).
 152  *
 153  * USIG_PROCESS_LOADED
 154  *     This is called after the executable file has been loaded into the
 155  *     new process context.
 156  *
 157  * USIG_PROCESS_RUNNING
 158  *     This is called immediately before the main entry point is called.
 159  *
 160  * USIG_PROCESS_EXIT
 161  *     This is called in the context of a process that is about to
 162  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 163  *     been sent).
 164  *
 165  * USIG_PROCESS_DESTROY
 166  *     This is called after a process has terminated.
 167  *
 168  *
 169  * The meaning of the dwFlags bits is as follows:
 170  *
 171  * USIG_FLAGS_WIN32
 172  *     Current process is 32-bit.
 173  *
 174  * USIG_FLAGS_GUI
 175  *     Current process is a (Win32) GUI process.
 176  *
 177  * USIG_FLAGS_FEEDBACK
 178  *     Current process needs 'feedback' (determined from the STARTUPINFO
 179  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 180  *
 181  * USIG_FLAGS_FAULT
 182  *     The signal is being sent due to a fault.
