I just tested generators and found a memory leak. (Has nothing to do with generators). The following code adds one to the overall refcount and gc cannot reclaim it.

def conjoin(gs): def gen(): gs # unbreakable cycle gen # unless one is commented out With current CVS: ...

One ref may be leaked the first time gc.collect() is called with garbage (23150 -> 23151). But after that, no more refs are leaked (ref count stays at 23151).

No, this is not the point. Don't call the function at all, just execute the above code and call gc.collect(). You will see one reference eaten every time you repeat this.
