[python-win32] MemoryError: can I use more?

[Greg Antal]

Dear Angelica:

2.2 GB is essentially the largest integer you express with 32 bits 
(2^31), and therefore the largest quantity of memory for which you can 
define an address. There are some tricks that really sophisticated 
programmers can do that let you use more than that, but I don't know how 
to do it. If you want to access more memory, you have to go to a 64-bit 
machine and operating system.

I have managed to keep memory footprint low, but have found that, independent of the physical RAM of the machine, python always gives the MemoryError message when it has occupied exactly only 2.2 GB. I have tested this in 4 different machines, all with memory of 3 to 4 GB... I'm amazed.
