FWIW, I agree completely.  I didn't write this code from
scratch, I heavily leveraged it from elsewhere (don't
recall exactly where, maybe xentop?).

If necessary, I will rewrite the callers and API but
I was just trying to fix an annoying bug expeditiously.
Let me know if you won't accept it as the one-line
ugly fix.

Still a problem.  Konrad filed an internal bug report
(Oracle has an Exchange-like mail server that is eat-
your-own-dog-food) but the US holiday weekend, which
many turn into a whole week, means it's probably not
even getting looked at yet by Oracle's IT group.

It may be unrelated to the xen.org server change but
the coincidence is suspicious.

Interestingly, I got precisely one xen-devel email in
the last week which is what led me to the spam filter
theory... though I have gotten every xen-changelog email.
