Scanning through my local phpxref'd copy of the trunk source it looks like
wp-cron is called on the "init" hook if we are currently not already doing
cron (see /wp-includes/default-filters.php lines 89-90).

Whether or not anything currently uses cron is another question.
Looking around there does seem to be a number of references to
wp_schedule_single_event - notably for pings and future posts.

I've just tried a future post on my test blog - now I wait to see if it
turns up....
