except if I run it under my latest 2.4 build, where I get 524288 ...

I get two different values:

-1.90734863281e-06
-2.14576721191e-06

on this hardware (faster than the PC I'm using right now, but still not a
very fast machine).  let's check a faster linux box:

$ python2.4 test.py
-6.91413879395e-06
-1.90734863281e-06
-1.90734863281e-06
-1.90734863281e-06
-1.90734863281e-06
-2.14576721191e-06
-1.90734863281e-06
-2.14576721191e-06
-1.90734863281e-06
-1.90734863281e-06

if I keep running the script over and over again, I do get individual

-1.19209289551e-06

items from time to time on both machines...
