Yoshi, any thoughts on this?

Comment 3

[Denis Palmeiro [:denispal]]

Might need to run something like js::CancelOffThreadParses() somewhere at the beginning of shutdown so we don't try to dispatch a runnable when main thread event processing is finished.

Denis should be a better person to answer this, since he has been working on bug 1652126, and bug 1661555

Comment 9

[Denis Palmeiro [:denispal]]

I've tried reproducing this on try, but it seems to occur too rarely so will need to fix it blindly. We could try registering a shutdown observer in the scriptLoader that cancels all active requests so the runnables don't get dispatched past that point.

Attachment: Cancel all off thread compilations at Shutdown

Register a shutdown observer for scriptloader and cancel all script load requests upon observation.

Comment 13

[Denis Palmeiro [:denispal]]

It seems this can also be occur from the compilations dispatched by ChromeScriptLoader as well. I was able to reproduce one of those crashes on try coincidentally:

So this may also need a shutdown observer to cancel off thread compilations.
