This also appears to fix a bug I had reported that did not involve
collective calls.

Hello to the list,
I came to a problem running a simple program with collective
communications, on a 6-core processors (6 local MPI processes).
It seems that the calls to collective communication are not
returning for some MPI processes, when the number of processes is
greater or equal to 5.
