Comment (by peterwilsoncc):

 I've reviewed the history of cron spawing.

 * [3512] - WP-Cron introduced
 * [3514] - `wp_cron()` added to the `shutdown_action_hook()` function


 * [3561] - moved from `shutdown_action_hook()` to `init`
 * [10521] - moved to `sanitize_comment_cookies`
 * [20652] - moved back to `init`

 Unfortunately most of these commits are from a time before detailed commit
 messages so there's not a lot of context beyond the commit messages.
