--- Comment #6 from Geoffrey Garen <ggaren at apple.com> ---
Two promising places to clear lastException:

(1) ~JSLock()

(2) A zero-delay timer

The purpose of lastException is to provide an out-of-band accessor to the exception thrown by the current task / micro task. So, it's OK to throw it away after the task / micro task ends.
