What exactly are the semantics of this very strange call? What does it
mean for the request to be completed? I'm guessing that a completed
request means that the data has been successfully copied into the
user-provided buffer, but that doesn't appear to be significantly
different behavior from MPI_Bsend().

I suppose maybe you could use this function to queue up buffered
message requests? But in that case, calling MPI_Ibsend() when there is
insufficient buffer space available would have to not be an error and
I certainly couldn't find anything in the standard on that topic.

Comments?
