------------------------------------------------------------

Are you certain that this is the right behavior?  If we disallow new transactions, then existing EJB sessions (for example) might fail to be completed.

Since the transaction manager is not considered an "entry point" in terms of graceful shutdown, it should not respond to a graceful shutdown other than perhaps registering outstanding transactions with the shutdown manager.

> We will handle suspend for JTA and JTS by disallowing new transactions and then block the suspend thread until the count of active transactions drops to zero. We will also suspend the recovery manager.
> We will *not* do graceful shutdown for the optional XTS subsystem. For example an incoming XTS request for an existing transaction will be blocked. 
> Question: should we
> - raise a new JIRA for this XTS case;
> - document the deficiency and see if there are complaints;
> - document the deficiency and fix it in a subsequent release
