------------------------


In preparing for an advanced admin class, I was playing with jobs with processes
which escape the process group.  As my job, I'm using a script that does a
setpgrp call to create a new process group.  I found that the setpgrp call will
silently fail unless I delay a little before the call.  I do not see the problem
if I run the script directly from the command line.  I have run into the problem
with both qrsh and qsub.

I will attach the script and the output from a success and a failed run.  By
looking at the script and the output files, the problem should be clear.
