Minor Description
In the current implementation, should the broker be deleted via delBroker, any pending transactions (getObjects(), method calls, etc) involving that broker remain in-flight until they time out. I think a better approach would be to abort these transactions by raising a "broker deleted" exception.
Also, I believe the same argument can be made in the case of an unexpected broker disconnect that occurs when managed connections are in use. I'd propose that the console should not only abort any pending transactions, but also delete all agents accessed via that broker.
Opinions?
