It may not be worth the trouble.

When I run Neville's stack saving test here with Windows Defender's RTP 
on the 8MB stack save takes a little over 8 seconds.

And when I turn RTP off it takes a bit over 7 seconds.

So while RTP is a clear conributor, it doesn't account for most of the 
speed loss on stack saves.


@Brian Milby: When you were looking up the stack serialization in the 
code, did you see anything which might explain why this slowdown is only 
evident on Windows but not Mac or Linux?
