 Whenever wordpress loads, it fetches all options with the
 wp_load_alloptions() function in the option.php file. There is a filter in
 the function before sending it to the cache: {{{#!php
 <?php
 $alloptions = apply_filters( 'pre_cache_alloptions', $alloptions );
 }}}.

 However, there is no way to hook into this filter in the theme or plugin
 because the theme or plugin are loaded afterwards.

 So the full array is always send to the cache.

 We were having trouble with a site that loaded all of the options with
 autoload 'yes' and it crashed with a memory limit exhausted error because
 there were too many options.

 An action needs to be added to hook into this filter or move the calling
 of this function some steps further after a theme or plugin is loaded.
