I had planned to have a patch for multiv4/v6 jails last month but it's not
yet publicly available. I have sent it off to some people for review.

In case the above is a successor of pjd's multi-ip v4 jail patch I can

possible locking issues I have never experienced).

All depends on how quickly you need it.
