Skip, I think this is irrelevant to the OP's problem.  You're telling us you
can save a few seconds running test_longexp on a box with barely enough
memory to run it at all.  Barbara is worried about shaving *hours* off it on
a box with gobs of memory to spare.

Still, I expect pymalloc will fix her problem (since malloc is the only
suspect on the list, it better <wink>).
