This is not much described anywhere, and even if it at one time was
one of the most central things about this project, that code now
slightly lagging behind. The procfs stuff is only tested/designed for
FreeBSD as that's what I'm using, but I'm guessing porting it to linux
or NetBSD would be easy. What it currently does is to allow me to
attach to bochs running Movitz and inspect memory and CPU state, or do
a backtrace, which at times can be very valuable for debugging.

I'll be happy to share any technical information I know, on request,
but currently I don't have time to actively write down all the little
details beyond what I've already done in the report (movitz.pdf) that
is available. I'm also not sure there would be much point anyway, as
many things have not stabilized yet.

Concerning GC in particluar I hope to produce some text (and code)
within a few months.
