> A couple hours into the tck I see everything freeze.  Looking at the threads there are a lot of waits on Queue.dispatchLock in addSubscription but one thread made it through to AMQMessageStore and is waiting at line 316 in flush on the countdown latch.
> Only problem I can see causing this so far is the countdown in asyncWrite not being in a finally block.  I don't see any exceptions in the log.... so not sure yet.
