This story started over a year ago when I discovered that Python never frees memory. Then I wrote a patch, and presented it at PyCon, but didn't have the time or energy to convince enough core developers to commit it. A few weeks ago, Tim Peters took it upon himself to clean up my patch, and committed it into Python's repository. This means that Python 2.5 will not have this bug! I'm glad to see that my work on this issue will finally be available to the public.
