>Fix:
the hint to this fix was found on the dfly list via google, and the fix
was done by simokawa@freebsd.org. I am just submitting it here so that
it gets applied to the FreeBSD tree.
(this patch is actually against RELENG_5)
(also, this is my first PR, so if I screwed something up, please let me
know so that I don't do it again)
