Summary: memory leak in nested def()
Initial Comment:
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
The above holds for Python 2.2.2 upto the current CVS
version. I didn't try yet to investigate this further.

Fixed. The compiler was leaking a reference to the int 0,
used to index an internal list.
