Subject: [PATCH]     - MGR: Use Sleep instead of Yield for the async thread
 loop.  On Posix         systems all Yield translates to is sched_yield but
 only if         HAVE_SCHED_YIELD is defined in the wxWidget config file.  If
 it isn't         defined it becomes a null op. The async thread doesn't
 really need         millisecond response times.  Have it check every 100
 milliseconds         for an RPC to process.
