The last time I checked, this was expected behavior per spec and non-determinism was due to some race conditions. But then I'm not too familiar with this area.
Hm... it appears that this problem no longer reproduces at least on this test. I'm gonna just remove waitUntilDone/notifyDone for now.

> it appears that this problem no longer reproduces at least on this test Perhaps it's more complicated when the script runs during load, as opposed to unload handler.

> unload onload, thank you autocorrection :)
