--- Begin a block of operations that check the completion counters in requests.

void MPID_Progress_start( void )

\subhead{Notes}
This routine is used to inform the progress engine that a block of code will
examine the completion counter of some {\tt MPID{\tt \char`\_}Request} objects and then call
one of {\tt MPID{\tt \char`\_}Progress{\tt \char`\_}end}, {\tt MPID{\tt \char`\_}Progress{\tt \char`\_}wait}, or {\tt MPID{\tt \char`\_}Progress{\tt \char`\_}test}.
\par
This routine is needed to properly implement blocking tests when
multithreaded progress engines are used.  In a single-threaded implementation
of the ADI, this may be defined as an empty macro.
