HANG: unregister drmgr event while in the event

From bruen...@google.com on January 30, 2014 14:45:17

DR's events are delivered from a temp list deliberately to avoid holding a lock, allowing unregistering from the event.

drmgr does not do that, and will deadlock in such a scenario. Yet the docs don't say you can't do it.
