Description

As it stands currently (and dating back to the Oscar days), if someone does a control-C, then the framework process just dies and there is no attempt to shutdown cleanly. If we add a shutdown hook, then we can cleanly shutdown the framework.

I am not sure if this would necessarily impact anyone who directly uses our launcher to launch the framework. I imagine there could possibly be an issue if someone uses our launcher, but registers their own shutdown hook. We also have the potential issue of a deadlock or some situation where we cannot exit, which could prevent the VM from exiting.

Any one have any thoughts?
