Zeroing of pages need not be done all at once.

Right now, if you have extra memory lying about (unusual yes, but read on),
it does not get 0'd until somebody grabs a "blank" page.  How about a mode
like "0 on reference"?  There is "copy on write" in some places, why not?
Then you only have to worry about 1 page at a time.  Extra swap space is not
costing you anything, why should extra memory?  Huh?
