 111  *           PROCESS_CallUserSignalProc
 112  *
 113  * FIXME:  Some of the signals aren't sent correctly!
 114  *
 115  * The exact meaning of the USER signals is undocumented, but this
 116  * should cover the basic idea:
 117  *
 118  * USIG_DLL_UNLOAD_WIN16
 119  *     This is sent when a 16-bit module is unloaded.
 120  *
 121  * USIG_DLL_UNLOAD_WIN32
 122  *     This is sent when a 32-bit module is unloaded.
 123  *
 124  * USIG_DLL_UNLOAD_ORPHANS
 125  *     This is sent after the last Win3.1 module is unloaded,
 126  *     to allow removal of orphaned menus.
 127  *
 128  * USIG_FAULT_DIALOG_PUSH
 129  * USIG_FAULT_DIALOG_POP
 130  *     These are called to allow USER to prepare for displaying a
 131  *     fault dialog, even though the fault might have happened while
 132  *     inside a USER critical section.
 133  *
 134  * USIG_THREAD_INIT
 135  *     This is called from the context of a new thread, as soon as it
 136  *     has started to run.
 137  *
 138  * USIG_THREAD_EXIT
 139  *     This is called, still in its context, just before a thread is
 140  *     about to terminate.
 141  *
 142  * USIG_PROCESS_CREATE
 143  *     This is called, in the parent process context, after a new process
 144  *     has been created.
 145  *
 146  * USIG_PROCESS_INIT
 147  *     This is called in the new process context, just after the main thread
 148  *     has started execution (after the main thread's USIG_THREAD_INIT has
 149  *     been sent).
 150  *
 151  * USIG_PROCESS_LOADED
 152  *     This is called after the executable file has been loaded into the
 153  *     new process context.
 154  *
 155  * USIG_PROCESS_RUNNING
 156  *     This is called immediately before the main entry point is called.
 157  *
 158  * USIG_PROCESS_EXIT
 159  *     This is called in the context of a process that is about to
 160  *     terminate (but before the last thread's USIG_THREAD_EXIT has
 161  *     been sent).
 162  *
 163  * USIG_PROCESS_DESTROY
 164  *     This is called after a process has terminated.
 165  *
 166  *
 167  * The meaning of the dwFlags bits is as follows:
 168  *
 169  * USIG_FLAGS_WIN32
 170  *     Current process is 32-bit.
 171  *
 172  * USIG_FLAGS_GUI
 173  *     Current process is a (Win32) GUI process.
 174  *
 175  * USIG_FLAGS_FEEDBACK
 176  *     Current process needs 'feedback' (determined from the STARTUPINFO
 177  *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 178  *
 179  * USIG_FLAGS_FAULT
 180  *     The signal is being sent due to a fault.
