During the beta period, 3.5 is open for normal maintenance (i.e.
anything that would be acceptable in a 3.5.1 release).

The 3.5 changes that need a +1 from Larry as release manager are the
ones where beta feedback reveals an "incomplete feature", where we
need to make a more significant change to resolve it that would
normally be disallowed on a maintenance branch (e.g. sorting out the
data model for PEP 492 after Ben Darnell's attempts to integrate
native coroutines with Tornado highlighted a number of shortcomings in
the original design).

The 3.4 branch also remains open for general maintenance until 3.4.4
goes out, at which put I assume Larry will put that branch into
security fix only mode.

I wonder: should we start putting some of these process details for
the different phases in the release PEPs themselves? Larry sent a good
summary to python-committers for 3.5 a while back, but they'd be
easier to find in the PEPs, and it would also make it clear which
aspects a new RM was keeping, and which they wanted to try doing
