The current CVS HEAD would go into a branch in Subversion (say,
branches/post-1.34-head). The 1.34.0 release branch would become the
development branch. Of course, developers will need to merge changes
over from branches/post-1.34-head to the development branch.

Yes, it's a pain. However, my experience with managing the 1.33
release series (and watching the 1.34 release series) tells me that
this is the right way forward. With each release, effort has gone
into bug-fixes for the release branch while HEAD has become the Wild
West, literally falling apart in the interim. It took months of
stabilizing HEAD to get to the point where we could branch the 1.33
release, many more months to to re-stabilize HEAD for the 1.34
release, and the time is proportional to the time that the release
branch is active. How long will it take to stabilize HEAD post-1.34?
If we're going to break the cycle of longer and longer releases, we
need to start each release from a clean slate... which means, in this
case, starting from the previous release and carefully merging
changes over from post-1.34-head to the development branch.
