Ralph Castain 2966206f58 Fix a race condition in the IOF and add some new user-requested features: 
1. fix a race condition whereby a proc's output could trigger an event prior to the other outputs being setup, thus c ausing the IOF to declare the proc "terminated" too early. This was really rare, but could happen.

2. add a new "timestamp-output" option that timestamp's each line of output

3. add a new "output-filename" option that redirects each proc's output to a separate rank-named file.

4. add a new "xterm" option that redirects the output of the specified ranks to a separate xterm window.

This commit was SVN r20392.

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
