Next time this happens, bump up the loglevel on the MS pbs_mom process with
SIGUSR1 to level 7 or 8, and send us a bit of the log that shows the loop.

There are many steps to setting up a job, each of which is a possible failure
point.  If it fails at an early point, then prologue isn't run.  Epilogue is
always run if prologue was run.
