lowering hits to processor

Thanks for the tips. 
And sorry to take so long to respond. 
Memory extensions. What a concept! 
Turns out that Dragon NaturallySpeaking uses them a lot. 
NatSpeak is a 32-bit program that needs more than it's share of memory, hence the extants. 
Wine manages them by "passing items like mmaps down to linux to manage."
So in short I think I'll stick with what I have.
