"there is a potential race condition in the SpoolManager between
the worker threads that actually process the mail and the action of the dispose()
method, which destroys the mailets"
JamesSpoolManager.dispose() now tells the spooler threads to terminate and then waits
(up to 1 minute) for them to complete.

The problem is that transport.JamesSpoolManager does not implement the
dispose method. It should implement dispose() to wait till all currently
executing processors shutdown gracefully. Todo this it will need to make sure
run() shuts down properly.
