My program seems to be working OK under MPICH2 1.0.5p4, which I just
built and installed on the 3-machine test cluster.  I ran several test
cases without any visible problems.

Correct, except they already agreed to try and upgrade to MVAPICH2 1.2
altogether, at some point in the near future. Still, it's very nice to
know that 1.0.3 might also be an option (in case upgrading to 1.2
isn't acceptable for some reason).

Thanks,
Nicolás
