well, I think that was the earlier workaround; the multi-IP jail
includes one of the patches that actually fix the problem; but the fix
for this case really just is a fraction of the change.

What I was thinking was this commit to head and the PR mentioned
there:
http://svn.freebsd.org/viewvc/base?view=revision&revision=186948

Note that 7.1 or earlier won;t have the prison_check_ip4() function,
different byte order requirements etc (and not IPv6 support).
It's s pretty short thing but has to be "converted" correctly.

I might be able to do that later today.
