 I've been debugging a site problem which turned out to be one of the cron
 actions resulting in a memory limit breach, and so PHP did a fatal error
 in the middle of the cron loop. (It's a high-traffic site so it has
 `DISABLE_WP_CRON` with system cron pinging wp-cron.php every minute.)
 There is currently very little debugging hooks provided in `wp-cron.php`
 to help diagnose why and where a scheduled event hook is failing.

 Some ideas for how `wp-cron.php` could be improved to facilitate debugging
 (and also to help with general logging):

  * Return a status message pinpointing at which point `wp-cron.php` exited
  * Return relevant HTTP status codes
  * Allow `die` behavior to be overridden, similarly to how `wp_die()` is
 used elsewhere
  * Add hooks before before and after each level in the triple-nested crons
 loop.
