I suppose you could have some sort of adaptive polling scheme that
spins polling for a while and then sleeps waiting for an event.
However, as Michael said, it's probably better to use pipelining and
post multiple send work requests. This hides the latency of getting a
completion event by keeping the HCA busy.
