Assembly Interpreter/Embedding C

[Tom Culliton]

I actually know several tricks for doing this (from my debugger
development days) and all of them would require some C code.  Don't
forget that executing arbitraty assembly code can get you in all sorts
of trouble.  It might actually be worthwhile digging around to find a
virtual 386 software emulator and writing a python binding for it.
That way you won't bomb your python interpreter when you mess up.
