Well, certainly that's not supposed to happen, but anecdotal reports
like this provide little basis for discussing what we ought to do
about it. It seems likely that raising the timeout would do nothing
except allow the stuck state to persist even longer before failing.
(Keep in mind that the existing timeout of ~2 min is already several
geological epochs to a computer, so arguing that spinning another
couple minutes would have resulted in success seems more like wishful
thinking than reality.)
