Which version of MPICH? MPICH 1.2.5 changed what it expects the P4_RSH_COMMAND
to do - the 1.2.4 and previous versions were ok if the RSH command used to
startup the job exited before the job completed, 1.2.5 considers it an error.

In Condor, we don't use a real RSH to start up a job, so we have an RSH
"in name only", and it exits before the job completes. We do plan to 
come up with a workaround, but it'll be a while before that gets into 
Condor.
