The fix was committed to head (260553) on 1/11/14 and was supposed to be
MFC'd in one week. See
http://svnweb.freebsd.org/base?view=revision&revision=260553. I don't
see that it's happened as of r261643.
I have cc'd David Chisnall. Perhaps he can address it.

Probably a little while. 10.0-RELEASE was just finalized last moonth. If
there's going to be an 8.5-RELEASE it will probably be next. Otherwise,
9.3-RELASE will probably be next.
