Comment (by ryan):

 In IRC we discussed putting the protocols array in a
 wp_allowed_protocols() function and using the kses_allowed_protocols
 filter on it.  wp_kses() and esc_url() would use this function.  The
 function can make the array static and perform the filtering only once,
 avoiding thousands of apply_filters() calls.
