The service controlling the thread (pool?) will depend on the 
deployment.  When the deployment is stopped, the thread pool is shut 
down and all executing threads are interrupted.  The service then waits 
until the the thread pool terminates before completing the undeploy.

The key is to make sure the thread pool service depends on the deployment.
