There was a problem hiding this comment.
good idea to set it to null request and (sanity) check it later...

This pull request addresses the problem of not completing non-blocking point-to-point communication operations. It is hypothesized that the lack of completing requests causes some communications libraries to run out of resources for large, long-running runs. The modifications in this pull request should ensure that any non-blocking operation that is posted will have a matching call to complete it (MPI_Wait or MPI_Test).
The modifications represented by this pull request are intentionally minimal and do not change the fundamental communication approach or implementation.
