I've been using Scientific.MPI lately and came across some strange
behaviour. When working on cluster running MPICH 1.2.1..7 and running a
script which uses commands.getstatusoutput() or commands.getoutput(),
reduce/send/receive calls don't work. I get 'Internal error: msg packet
discarded' errors coming from gmpriv.c:814. But when working on a cluster
running MPICH 1.2.2 they work fine. Using os.getcwd() instead of
commands.getstatusouput('pwd') works fine on both too.
