The current design creates HOL blocking on the Finished message in some cases.  It might be OK not to block on this, but it would require some careful analysis to ensure that we have understood the implications properly.

A safer alternative might be to find other ways to ensure that Finished arrives in a timely fashion, though that could require some contortions on the packet format.
