       For example: when a message arrives at orterun, we want the

       seem good about doing) and then we want orterun to process

       long time before the OS schedules orterun to run again
       (particularly if there is no IO event to wake it up).  Hence,
       routed OOB messages (for example) may be significantly delayed
       before being delivered to MPI processes, which can be

       it should; but when it *is* doing something, we do not want it
       to be unnecessarily delayed because it voluntarily yielded the
       processor in the middle of its work.
     
       For example: when a message arrives at orterun, we want the
       OS to wake us up in a timely fashion (which most OS's
       seem good about doing) and then we want orterun to process
       the message as fast as possible.  If orterun yields and lets
       aggressive MPI applications get the processor back, it may be a
       long time before the OS schedules orterun to run again
       (particularly if there is no IO event to wake it up).  Hence,
       routed OOB messages (for example) may be significantly delayed
       before being delivered to MPI processes, which can be
       problematic in some scenarios (e.g., COMM_SPAWN, BTL's that
