Thanks for the support!

However, I think Matthias wants read access to the release repo because he's

Again, this is what RC2 is for (and RC1, for that matter; apart from 20+
asyncio patches there really isn't much of a difference between RC1 and
RC2). Larry may legitimately feel uncomfortable with what he's got on his
local drive and prefer to tweak some things before telling people "go ahead
test with this" -- the difference is that if he was working on new *code*,
he could just not commit his work-in-progress, but since here he is
assembling the final sequence of *revisions*, he prefers just not to push.
(Georg alluded to the fact that you can undo changes in a public repo after
they've been pushed, but I suspect he's referring to hg backout, which
creates extra revisions, rather than a remote version of hg strip, which
would go against the philosophy of DVCS. Either way, Larry's use of Hg is a
totally legitimate workflow.)

And that's great, of course. But what is really gained by giving Larry
trouble over a few days' worth of delay, at most?
