--- Comment #2 from Brady Eidson <beidson at apple.com> ---
One idea for part of this:

All of the IDB ActiveDOMObjects guard their own "postTask" which has a guard lock around the scriptExecutionContext(). They also use that lock inside their "contextDestroyed()" observer.

That will definitely solve the first big problem - the race with the scriptExecutionContext itself existing and being active.

Then we just need to solve "the thread runloop itself may no longer be active enough to use."
