Since I can't reproduce the failure, I can't confirm that it is now fixed, but the lack of volatile is clearly a bug so should be done anyway. Tested by running the test locally to make sure nothing breaks.

The fix looks good. Also, I have no objections against adding a comment.
The event listener thread sets the flags and the main thread checks them.
Making flags volatile should be enough.
Clearing the flags in the main thread was also a bug before the fix.
