 We have this:

 {{{
 // Ensure these global variables do not exist so they do not interfere
 with WordPress.
 unset( $wp_filter, $cache_lastcommentmodified );
 }}}

 It used to include more variables, but they were removed when a few of us
 took an axe to wp-settings.php back in 3.0.

 I suggest we remove both. $cache_lastcommentmodified can easily become a
 static variable within that function (I mean, we're dealing with pre-1.5
 code here) and a lot of things would be broken if people overrode
 WordPress globals prior to startup, not just $wp_filter.
