Wow -- neat! We certainly didn't think of this case. :-)

A good idea; yes, we can do this. I'm sorry that it won't make the
1.2.3 release, though. I'll file a ticket.

FWIW: we're actively working on native LSF support in Open MPI such
that this kind of rsh tomfoolery won't be necessary in the future.
We hope to have it ready for the 1.3 series.
