Subject: [PATCH] Cron API: Make wp-cron.php non-blocking where possible.

This should make cron spawning faster by ensuring requests to wp-cron.php return immediately regardless of transport method. It is enabled only on recent PHP versions with fastcgi, due to historical bugs and availability of `fastcgi_finish_request()`. This needs testing on a range of platforms, to help determine if it's safe to use in other contexts also.

Props vnsavage, johnbillion, jnylen0.
