Ok, this is not a sec issue, because gFactoryOps holds strong references to FactoryOp objects, but if we don't do the cleanup, the op is not removed from gFactoryOps array and that leads to a shutdown hang.

This all can happen when parent sends PermissionChallenge to the child and the child dies instead of sending PermissionRetry back the parent.

I guess the permission stuff is still used by extensions.

I can definitely simulate this issue with dom/indexedDB/test/browser_permissionsPromptAllow.js test

We should fix it.
