Besides, there is all sorts of fun to be had in the "really really small 
OS" department. I've been toying with the idea of how to architect a 
micro-kernel with only about 5 systems calls (remap memory, create 
process, kill process, switch to process, jump to on interrupt, fixed 
size IPC). If I wasn't already +3x booked for time, I would be figuring 
out how to wright it, in D.
