With current CVS:
>>> gc.collect()
0
[23150 refs]
>>> conjoin(1)
[23160 refs]
>>> conjoin(1)
[23170 refs]
>>> gc.collect()
8
[23151 refs]
>>> conjoin(1)
[23161 refs]
>>> conjoin(1)
[23171 refs]
>>> gc.collect()
8
[23151 refs]
>>> conjoin(1)
[23161 refs]
>>> conjoin(1)
[23171 refs]
>>> gc.collect()
8
[23151 refs]
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).
