this new system gets rid of the $may_cache switch in hook_menu(). hook_menu is now called only upon module enable/disable and admin/menu. this is outstanding. however, we no longer have a place to stick our drupal_add_css() and drupal_add_js() type calls.
so, lets create a new hook_signal($op) which fires at various points during a request. Initially, it replace hook_init() and hook_exit() with $op=precache, $op=postcache, and $op=exit. We shall also add $op=postbootstrap which is where the drupal_add_css calls will go.
This is an unneeded level of abstraction. We already have signals that fire at various points during a request. They are called hooks. They are faster and more descriptive than hook_signal($op). hook_precache hook_postcache hook_exit etc.
