Well, I've got this word processor...

One of the things I've noticed is that it's a bit slow on low-end
machines. I've been looking at speeding up the VM via patches, but I'd
be fascinated to know whether an optimising compiler would help. It's
about 4000-odd lines of Lua, IIRC.

The version on the web site runs on a stock Debian lua5.1 installation
(although with extensions for the screen I/O), so there shouldn't be any
gotchas.
