Unfortunately the particular patch from Olaf is presumably covering up another bug that other people (including Olaf) had hit. So reverting it is going to introduce a different regression. I think this particular problem has _already_ bounced back and forth once. But I haven't been keeping count as most of the relevant patches weren't cc:ed to me. -- Mathematics is the supreme nostalgia of our time.
