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

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.). */

* If we are the selected module, then we must be a singleton

*
* (1) if we try to play the role of the HNP, then any child processes
* we might start via comm_spawn will rely on us for all ORTE-level
* support. However, we can only progress those requests when the
* the application calls into the OMPI/ORTE library! Thus, if this
* singleton just does computation, the other processes will "hang"
* in any calls into the ORTE layer that communicate with the HNP -
* and most calls on application procs *do*.
*
* (2) daemons are used to communicate messages for administrative
* purposes in a broadcast-like manner. Thus, daemons are expected
* to be able to interpret specific commands. Our application process
* doesn't have any idea how to handle those commands, thus causing
* the entire ORTE administrative system to break down.
*
* For those reasons, we choose to fork/exec a daemon at this time
* and then reconnect ourselves to it. We could just "fork" and declare
* the child to be a daemon, but that would require we place *all* of the
* daemon command processing code in the ORTE library, do some strange
* mojo in a few places, etc. This doesn't seem worth it, so we'll just
* do the old fork/exec here
*
* Note that Windows-based systems have to do their own special trick as
* they don't support fork/exec. So we have to use a giant "if" here to
* protect the Windows world. To make the results more readable, we put
