My suspicion is that building Python for an 64-bit address space is still a somewhat academic exercise. arbitrary 64-bit systems, perhaps. the first Python system I ever built was deployed on an LP64 system back in 1995. it's still running, and is still being maintained.

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).
