Thanks, guys. I've found ways to speed things up a decent amount, and put an
alpha of my SuperStack up on Scrapple, though I renamed it to TempAlloc because
I
don't like the name SuperStack. See D.announce and

One thing I forgot to mention in the orig. post: This happens in

to
actually use multithreading yet.
