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

require OOB messages for wireup, etc.). */
