I can see that you would run a 64-bit version of Python on a system
where no 32-bit mode is available, or where certain libraries are only
available for 64-bit mode, or where the performance of the 32-bit
mode is inadequate. However, I would expect that you "normally"
cannot exercise the "large collections" feature of Python 2.5
on such an installation, because you have not enough memory
(in particular if the system was built in 1995).
