Comment (by tombarta):

 Is this a ticket about `E_NOTICE` errors or about caching?  These are
 orthogonal issues and it's confusing to see discussion on both of them in
 a single ticket.  IMHO, Wordpress should not be producing `E_NOTICE`
 anywhere.  The pattern that typically fixes this without affecting large
 swaths of code is converting
 {{{
 if ( $my_super_option != '' ) ...
 }}}
 into
 {{{
 if ( isset($my_super_option) && ($my_super_option != '') ) ...
 }}}

 For readability's sake, it's best to avoid conditional defining of
 variables, so checks like {{{if ($option)}}} make sense without
 referencing undefined vars.
