At the moment, yes. OMPI's asynchronous progress is "loosely
tested" (at best).
OMPI's threading support is somewhat stable for some devices (e.g.,
not OpenFabrics-based networks), but it's still somewhat new, so
feedback would be welcome here.
Per my other mail, depending on your network/etc., you might get
asynchronous behavior using non-blocking MPI functions.
