As written I think it could potentially fail, but what I actually care
about is something weaker that should be true. Assert: nothing lost.

f0e9a2a081 Fix PutBlock after Release bug 
There is logic in the broadcast hub to skip the outer acquire if there
is an outgoing release, since the data will be written out through the
release channel. However, this will cause an issue in the case of
PutBlock requests. If the tail beats of the PutBlock show up after the
outer release has already been sent, the data will be corrupted.

The fix is to make the outer release block if there are pending
inner PutBlock beats.
