 Remarks 

 KbdSynch blocks all other threads within a session until return from the 
 subsystem to the router.  To ensure proper synchronization, KbdSynch 
 should be issued by a keyboard subsystem if it intends to issue a 
 DosDevIOCtl or access dynamically shared data.  KbdSynch does not protect 
 globally shared data from threads in other sessions.
