Fix for journal committing.

Sometimes we could previously, under load, report that journal items were
committed when they were not.  Try to track the uncommitted state more
carefully now.

I'm surprised that this didn't cause trouble earlier; it seems that
unlocking an unlocked mutex raises no errors (but under heavy load, when
the mutex is locked by another thread then unlocking it can cause trouble).
