Python gets its information about memory (and allocates its memory)
from the operating system.  This is not discussed in the documentation
because it's more or less taken for granted -- that's what one should
assume of any app or language unless other behavior is documented.  If
your Win/2K, Win/XP, or whatever, is able to see your new memory and
make it available to apps (and I see no reason why not), Python, like
any other normal app, should be able to use it just fine.
