I have a gram job. I add a listener to that. When the job completes (or fails),
in the listener, I call job.destroy(). This tries to shut down the notification
container. That happens (among other things) by signalling all the service
threads in the pool, and then waiting for them to complete. However, since the
wait happens in one of these threads, it cannot complete unless it times out.

This might be viewed from two separate point of views. 1) it's a user's bug - 
you shouldn't be shutting down the notificatin consumer container from within 
one of its threads, 2) it's a container issuse - when waiting for its threads 
to shutdown, it should ignore the container thread that is the same as the 
current calling thread.

I think probably both things should be fixed.

I think this is a reasonable usage scenario (calling the destroy from the
notification call). Otherwise I would have to artificially create a thread (or
queue) just for the purpose of destroying GRAM jobs.

Fixes committed to globus_4_0_branch and trunk. If the calling thread is one of 
the container threads it will be ignored when waiting for all the container 
threads to finish. Also, added a test case for this scenario.
