BTW, have a look at the step out of range code.  The theory is that the 
target be presented with a range of addresses and it run until it leave 
that range (as is the case with a step or next).

The implementation breaks the theory -- the code didn't consider threads 
and multi-threaded interactions.  As far as I'm concerned, to fix the 
theory we need to disentangle threads.
