If anything this should improve the experience of bisecting, because
you'll be able to bisect known-good csets on m-c and only at the end
step in to the merge csets which may or may not be good.

Right now we say that when people push a patch queue to m-c every
patch should be green, but in practice that's often not the case.
Right now when you bisect you have no way that I'm aware of to say
"bisect only the tips of pushes", because hg doesn't store that
information, so you end up bisecting through many bad csets.
