Fair enough.  If the need arises, it's easy to lay down a tag after the
fact, by copying:

    svn copy svn+ssh://svn.freebsd.org/base/head_at_181904 \
      svn+ssh://svn.freebsd.org/base/tags/pre-mpsafetty

But since the initial commit was pushed to svn in one changeset, the
need for that is a bit small I guess.  Doing it later should also be
ok too.
