Thanks for reaching out to him. So if I'm reading this correctly,
there's little point in filing a FreeBSD bug because it'll be
dismissed as unfixable.

This leaves us in rather a nasty position. Sure, we could rewrite
rmtree() as Thomas suggested upthread, but I'm still of the opinion
that that's smearing lipstick on a pig. rmtree() is the least of
our worries: it doesn't need to expect that anybody else will be
modifying the target directory, plus it can easily restart its scan
without complicated bookkeeping. I doubt we can make such an
assumption for all our uses of readdir(), or that it's okay to
miss or double-process files in every one of them.

I'm still of the opinion that the best thing to do is disclaim
safety of storing a database on NFS.
