Hmm.  I don't completely follow, but does this explain why waf
always succeeds on the second attempt?  If not, it might be
something weirder... but then again, if you're following it up on
the waf-user list, then it's no longer my concern.

I'll check it out tomorrow.  If it works, I'll spend another few
hours on waf -- particularly, trying out things that are more
likely to fail.


If you're willing to follow up on any more cases like this, then I
think I'll be willing to keep on waffing.
