I snipped some of the diff's content that was also in the PATCH's first 
version, and that probably screwed it up.

There's a way to that correctly, right? Or should I just send the entire 
diff so that it shows up in each new version of the patch, for context's 
sake?

Still need to add debugging in instruction
execution, and perhaps add a better VM
constructor for debugging, that can still
allow for toggling the debug mode in the
middle of execution.

Later on, swapping over printing to stderr
to logging with and without debugging would
probably be more suitable.

Alright, got that fixed.
We're probably going to want to switch to 
logging instead of stderr printing, but

Debugging inside the CPU would involve passing around the debug flag
and the stderr lock into the CPU module, which seems simple enough,
but might get unhandy, especially since StderrLock has an associated
lifetime, which might propagate some complexity.

I'm not sure if there's a better way of handling it as of now,
but if you've got any debug design you'd rather implement, I'm all
