I agree wholeheartedly. I wasted quite a bit of time tracking this
problem down in one of my programs that ran perfectly under BSD for
the last 10 years. It is also the worst kind of bug to chase -- the
kind where one's mental model doesn't match up with what the low-level
machinery is doing.

I can try, but my batting average with such policy-issue type requests
is very low.

That might be a good way to deal with the issue, especially since one
can't be totally sure if the mapping has been turned off via the
sysctl that Maurice mentioned. (Thanks Maurice! I didn't realize it
was available, but as you pointed out, flipping it may well result in
other programs losing their v4 mapping.)
