 The wp cron functions are very picky about argument types.  For example,
 if I do this:

 {{{
 $post_id = '123';
 wp_schedule_single_event($time, 'foo', array($post_id));
 wp_clear_scheduled_hook('foo', (int)$post_id);
 }}}

 ..the hook won't get cleared as expected, because the type of the post_id
 argument doesn't match (string vs int) even though its value is the same.
 That's an easy mistake to make: in wp-includes/post.php, post ID's are
 passed around that are variously strings or ints at different places in
 the code.  I'm not aware of any code that currently breaks, but it's a bug
 waiting to happen.

 To add to the confusion, Wordpress and Wordpress-mu store cron hooks with
 different post ID types: Wordpress uses a string, Wordpress-mu uses an
 int.

 I'm not sure what the solution is, but it's probably worth noting
 somewhere.
