Good tip, Dennis.

However I'm pretty sure you should only do that for templates that are used on every page of your site. You can conserve memory by adding page specific and action specific templates to the $globaltemplates and $actiontemplates arrays (respectively) at the beginning of the file that uses them instead of adding them to global.php. Profile.php and usercp.php are good files to look at to see examples of this.
