[OMPI users] Blocking communication a thread better then asynchronous progress?

[tomek]

Hi

Since I discovered, that asynchronous progress does not work too well,  
here is my question:

Is doing blocking communication in a separate thread better then  
asynchronous progress?
(At least as a workaround until the proper implementation gets improved)

Of course I will test it, but perhaps somebody has some experience  
already.
