Comment 98 for bug 294712

Not really sure of a good alternative, the two methods can't really be merged into one helper method. I can indicate in both files that they are dependent on each other (more accurately, nsContentBlocker is dependent on nsPermissionManager), would that be enough? I can also include a test that compares with entries stored and found in the permission manager vs. nsContentBlocker which will fail if something changes (although it won't be 100%).
