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.
