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 scream.
