Comment 257 for bug 113201

I can reliably reproduce the following failure with tryserver unit tests:
*** 41223 ERROR TEST-UNEXPECTED-FAIL | /tests/dom/tests/mochitest/geolocation/test_manyWindows.html | Error thrown during test: windows[i] is null - got 0, expected 1

There also seem to be some leak test issues:
