all the /cc stuff is related to the interpreter. by wrapping code in
with-call/cc you're trading execution time and memory space for the
ability to have continuations, sometimes it's worth the tradeoff,
sometimes it isn't.

i once (quite a while ago) profiled a one of my ucw apps, about 0.5%
of the execution time was being spent executing defaction forms. if
you want faster ucw apps then implement two things: 1) optimized
stream writing (on openmcl 40% of the time is spent in
%write-to-buffer (or whatever it's called)) and 2) component caching
(another 30% is spent rendering components).
