Actually, that's not true.  The garbage collection in recent 
Python versions (I think 2.0+, but I'm not positive) can indeed 
detect cycles.  Of course, if you know that you've got circular 
references, you're likely better off using weakrefs anyhow, but 
it is possible for Python to release cyclic garbage.

That being said, the problem here seems to me to be the OS memory 
management, not anything to do with Python.
