*Sigh*. This is why it's better to look at concrete proposals than to
discuss without them... we all assume different things about the
unsaid details.

When we release 1.34.0, we switch to Subversion. The repository
layout (documented at
BoostSubversion) contains two branches, "stable" and "devel". Changes
go into devel first, get tested, then migrate to the "release-ready"
stable branch. IIRC, this is one of the recommendations in Beman's
proposal, and it's much easier to enforce in the world of Subversion.

When we switch to Subversion, the 1.34.0 release branch becomes both
"stable" and "devel", giving us a clean slate. The current CVS HEAD
becomes a branch (branches/post-1.34-head). Developers can migrate
changes from post-1.34-head to "devel", where they will be tested,
fixed, and eventually moved to "stable" for a release.
