That's what's so confusing to me. I did restart the server, and I'm
still seeing the old code. There aren't even any pyc files around for

generated properly, at least somewhere.)

Hmm, I'm using self.writeln() to write out the html, I don't remember
off the top of my head if that's from mod_python itself or from the
servlets...
