Something to try, which would separate the two types of leak: Run your
program in a separate namespace of some sort (eg a function), make
sure all your globals have been cleaned up, run a gc collection, and
then see if you still have a whole lot more junk around. If that
cleans everything up, it's some sort of refloop; if it doesn't, it's
either a global you didn't find, or a C-level refleak.
