[issue2246] itertools.groupby() leaks memory with circular reference

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

It looks like the problem is that the internal grouper object becomes a
part of a cycle: keyfunc -> grouper(x) -> keyfunc(tgtkey), but its type
does not support GC.  I will try to come up with a patch.
