Aidan Skinner commented on QPID-1332:
-------------------------------------
The message arrival blocks on the synchronousQueue when it puts the message on
if it's full while holding the _lock. The QueueBrowser attempts to get _lock
while it's being created, if the synchronousQueue is full it won't get created,
if it's not created then the syncQueue won't empty so it won't unblock.
Fun for all the family.
> Opening a queue browser on a consumer when it's prefetch buffer has been
> filled causes a deadlock.
