Wow, this is pretty cool!
Note that the lguest implementation is a bit limited, but lguest doesn't
have a real ABI, so we can simply change it if we wanted to. I assume
you don't have that luxury.
In particular, you may want to get rid of the historical align constant,
and have explicit avail and used addresses.
Cheers,
Rusty.
