To get the leak in testgenerators, I think you make need to add GC to the teeobject as well as the teedataobject.

The teeobject has GC (hence the word 'and' in 'itertools.tee and its internal teedataobject' ;-) The problem with test_generators is that this also leaks:

def leak(): def gen(): while True: yield g g = gen()

leak()

It doesn't leak in 2.4. I'm using a little shell script to work backwards through the 2.5 changes to find out which one introduced this, although I somehow suspect it's the coroutine stuff... ;P
