yup. but this doesn't change the fact that, if you find something
that's broken and you fix it, it'll stay fixed. ;-)
on a more general note; we're now checking more stuff in the API,
which makes it slower. there's some stuff which, 99.99% of the time,
makes the API faster; so we do that. unfortunately some of the stuff
can't be fast and do the checks.
i wanted to link to a very funny cartoon about design compromise here,
but i can't find it on google. maybe i'll redraw it...
 and be maintainable, and readable, and portable, etc... you know the drill.
