For looking at memory on windows you might be able to make improvements 
to this class I wrote.  I was going to add memget() methods for getting 
individual items,  but it wasn't as useful as I was hoping it would be 
in checking my python memory use.  For that I need info on individual 
tasks, but this might be better for your use.

Cheers,
