test_list, and possible other tests, use a lot of memory when Python is
build in 64-bit mode. This causes heavy swapping when the machine doesn't
have a huge amount of memory.

I've filed this bug because an OSX box with 3 GBytes of RAM gets
completely unresponsive when trying to run test_list (due to heavy
swapping).

Apparently this has been fixed as part of r65335 ("Security patches from
Apple: prevent int overflow when allocating memory"), although it uses
sys.maxint where sys.maxsize may be more appropriate. Can you check?
