Now, this gives a true deja-vu. Python applications often rely on reference counting (in particular, that releasing a file object will immediately close the file), despite the language reference saying that this is not a Python feature, just one of the implementation. In addition, implementing a tracing garbage collection would either be tedious or have additional consequences on semantics: with a conservative GC, some objects may never get collected, with a precise GC, you have to declare GC roots on the C level. Things get more complicated if the GC is also compacting. See the current thread on the py3k list.
