Ok. I think it's time to revive Volker's original idea of reviewer-must-push
for *all* changes, even for master.

The fault is not entirely Andrew's, both Simo and I missed this
problem (along with the subsequent crash bug) in the review, so
this means we really didn't do a good enough job on this review.

Enforcing reviewer-must-push will concentrate the mind wonderfully
when doing reviews, as you'll have to add a signed-off-by line
in the push to master :-).

What do Team members think ? Do I have anyone to second this ?

Jeremy.
