We've been here nearly two years ago but I guess things have moved forward
enough so that ideas rejected then might be acceptable now.

When the pretest is released, hopefully soon, I suggest that a branch is cut.
I may be wrong but I think this is usual practice.  I don't think this will
mean that effort will be taken away from the release as many developers have
expressed an interest in seeing one.  It will, however, discourage adding
further changes which are not really bug fixes, and indeed, may introduce new
bugs.  In fact, I think there should be a strict rule that only changes that
relate to identified bugs be allowed on this branch.  There will also an
incentive to get the release out, so that normal development can resume on the
trunk.
