They are fixable but requires a lot of time to find and fix it, in the
meanwhile your program is leaking. It's a trade-off.

No, the GC of Python releases and objetos are not in use anymore.
Only in a very few situations this doesn't happens. About memory usage,
it's possible to setup GC to release memory more often than the default.
