But it doesn't need to if the page is going to overwritten before it
is hand off to the process. According to the stats coming out of my
page_alloc rewrite there are surprisingly few zeroed page requests
relative to the total number of requests. Having zeroed pages to
hand will reduce the latency of some things but won't make the kernel
