Comment 19 for bug 197781

Stuffing the overlay files with useless comments (eg. until they're 10 MB) allows to interrupt the loadOverlay calls. In this case, the testcase will fail - but I wouldn't expect it to work in this case anyway.
I didn't see any suspicious behaviour either, so maybe the testcase is just too simple for testing such edge case. Suggestions?

Otherwise, I'd suggest asking for first reviews...
