tradeoff the type of bsiter()

int is used all over the place for temporaries,
maybe this should be changed, I don't know.

Another thing to consider is that temporaries
are currently on 12 bits (and will be on 29
or 30 bits in the future), so int will always be
safe to store them.  We just loose the free
invariant of non-negativity.
