Description From 2006-02-22 17:07:05
Deadlock is due to non-daemon threads waiting on other non-daemon threads (and
other external resources), thus not relinquishing the worker thread and thus not
returning the worker thread to the work manager's thread pool. Since other
threads cannot be scheduled, the net result is a deadlocked DRS (if not work
manager in total).

Fix is to change Discover, Transfer, and TransferRequest {Worker}s to return
true from isDaemon method.
