All storing immutable objects in the memo dict does is slow stuff down, due to having a larger hash table, and on some other Python's causing hilarious levels of GC pressure.  Using http://paste.pocoo.org/show/421310/ as a benchmark, CPython get's a 2x speedup on the deepcopy portion, and PyPy a 20x.  Patch is attached.
