Comment (by cfinke):

 It appears to be reliant on whether a `>` character follows the last `<`
 character in the content being passed to `do_shortcode()`.  When there is
 no closing `>`, then `shortcode_parse_atts()` takes much less time to
 complete, probably because a lot of the string gets stripped or ignored.
