This was updated since I last looked at it, thanks for pointing that
out.

So there must be a leak that is related to how many qtrees you have.
Because even if I had 1600 qtrees, that shouldn't slowly eat up 6GB of
RAM, correct?

That said, I'll try the memleak detector you pointed me to, and read up
on how it's supposed to work.

Thanks for your help,
Marc
