Actually, it was only a synchronous MPI_Recv that did this in MPI, a 
synchronous
MPI_Send would have been even worse. Which is why MPI got the
asynchronous method MPI_Irecv...

Sounds like you just want a barrier or a condition primitive. E.g. have 
the sender
call .wait() on a condition and let the receiver call .notify() the 
condition.
