/*
PURPOSE:
    (This header file defines the "RELEASE()" macro for supported platforms.
     The release function should yield the processor from the processes that
     makes the call. This allows the UNIX schedular to arbitrate process
     priorities during spinloops based on the status of processes waiting 
     to run)
PROGRAMMER:
    (((Eddie J. Paddock ) (LinCom) (2/96) (--) (Realtime))
     ((Scott Killingsworth ) (LinCom) (October 1997) (OSF1 port) (Issue #1233)))
