It is supported. The TCP method in particular uses immediate completion
extensively. The pingpong test handles it correctly as well. If
BMI_post_recv() returns 1 then it skips the test loop because the
operation is already completed.

I am interesting in possibility of immediate completion for just

Immediate completion is indicated from post functions

I can't speak for all the methods, but the MX method does not
support any immediate completion for sends or recvs due to
potential races in the implementation. I do not think the IB
method allows it either but I defer to others.
