heap is a misnomer. its heap is userland.
kernal land uses paging.

both are incomplete in FPOS. I have working code from CoffeeOS(after several 
code rewrites) available for BOTH. Code syncing is appreciated.

The paging unit here repeatedly page faults.[TSS pages not allocated, IIRC]

This code is some of the most obscure C I have translated yet. Not one C 
programmer does it the same as another.

seems the maintainer here is taking some long holidays.

I have some linking issue i am working out. CoffeOS is at rjasmin,net.It 
builds, but I need to look at my linker.
Release: 4Nov2010
Will update the codebase on the site in a few hours, I have to update some 
other stuff.

My SVN setup got borked, so HTTP/FTP got setup instead.You need patch/diff on 
windows to sync your code.
