The devs get (essentially) 5 - 7 days to see 2 emails for all issues
that need looking at. While some do a LGTM, there was some assumption
that instead of filling up the reviews with +1/LGTM etc. That as long as
it passed tests and went through the countdown
(new/review/countdown/push) without complaint it was taken as read the
patch was OK.
If a dev wants to keep a patch on review longer then set the Tracker
back to whatever you need (i.e. put it back from countdown to review)
and I'll just move it on one again the next time.
