C:\>python

I can't switch to 64 bit right now. This is a dual Core 2 Duo machine
(2 CPUs, 2 cores each).

I've looked at the deallocation code for dict objects and I can't see
anything that should be affected by 64 bitness, at least not nearly
the degree described - it DECREFs all the keys and values in the dict,
calls PyMem_Free on its memory pool (if it was large enough to be
malloced, which this certainly was, and either adds itself back to the
dict object pool or deallocs itself (if its a subclass of dict).
