I'm currently doing busy waiting on BSY. But the problem is determining whether 
a zero means ready, or not yet set.

Well, in theory my current code should work. In practice I have to fix fairly 
trivial bugs first, which is time consuming given the lack of incremental 
compilation of the image and the long compile time (~10 minutes on my 1GHz box).

Would it be possible to dump state at some point in compilation and start a new 
compilation from there instead of restarting from scratch? Even if that 
generates multi-meg images it would be a huge improvement in efficiency of 
compilation.
