I haven't been very religious about posting my own development
builds on a regular basis. I ran into that performance bug as
well, and fixed it back in April. I'm pretty sure no one has that
fix other than me.

I'll do another beta release ASAP.

Is that a single file, or a bunch of files? That'd be a great test
case either way -- would you be willing to share the source input
and your build script? (Or if you already have, remind where
exactly I can find it -- I do recall your weblog post from a few
months back explaining your Markdown-based documentation system.)

I'm not entirely sure whether my current internal build performs
as well as Markdown.pl 1.0.1, but I think it does.

Interesting. I'm investigating now.
