 > Currently, it's a jumbled mix: `handle_404` both controls state ("let's
 see...looks like a 404 situation, so let's toggle `$wp_query`'s 404
 property to `true`") and acts on the state by printing headers.  Instead,
 one method should determine the current state, and another (with a filter
 or pass-by-reference action hook at the top) should do the header
 printing.  Then we could hold off on the headers until much closer to the
 time the templates get included and print them all at once.

 That would certainly make my use case simpler, and I'm selfish enough to
 think that's important. ;) Seems like a `nocache` flag would be needed,
 would that be stored on `$wp_query` too?
