Hi Sergio, memory should be freed up; if it's not getting freed, you
have a bug somewhere. Maybe you're not _unref()ing stuff you should be
unrefing?

You could try a leak checker to try to track the problem down. memprof
is nice and very easy to use:

Run your program with no input first, and nail the easy leaks. Then
start adding more data and see where new leaks appear.

If you want something more sophisticated, you could download a trial
version of purify:
