But if that redeployment is triggered by an attempt to overwrite an
existing unpacked war.....

At the end of the day, there is nothing we can really do about it - it
is the URLClassLoader that is doing the locking.

Alexy - can you describe how you are deploying?  I expect you are
deploying an unpacked war or ear?   If so, can you try deploying
a packed war or ear so that jboss copies it elsewhere before giving
the URL to the URLClassLoader.
