Strange -- this almost implies a race condition somewhere.
I don't see anything wrong with your application (other than it doesn't free
the communicators, but that's not an error).

That being said, the MPI-2 one-sided functionality (which is being tested by
the osu_get* and osu_put* tests) is notoriously difficult to get right. I
