I had forgotten about this.

I should ask my LSF contacts if this method still works with Open MPI
v1.3 (which natively supports LSF), or whether strange / interesting
failures occur because of the integration that mpirun.lsf does ends up
effectively conflicting with what OMPI's mpirun does internally...
