recentchanges for 10 minutes. In fact, 10 mins shouldnt even be required. If I understand correctly, this test is essentially asking the RC feed for four namespace 0 edits, any time in the past. This should always be an instant result.
This is wrong. RepeatingGenerator will ask the RC feed for the latest edit in the past (to be an indicator of "present") and three more edits in the future. Thus, it might not return an instant result for some sites. For English Wikipedia, however, it should return an instant result.
