That's not really what we're looking for. We're looking for a sort of drupal_reset_info($key) function that forces a reload of the data.

 Ah, indeed!  Make that 2 more attributes of an info hook:
 - It has a commonly-named rebuild function: drupal_rebuild_$singularNoun() (or something).
 - drupal_rebuild_$singularNoun() is called as part of the master cache reset function.

but this wouldn't be able to reset a static cache variable? would it? unless we had something like. I really like to two stage cache for things that might possibly only want to be cached per request...
function module_invoke_all_cached() {
  static $cache = array();

  $args = func_get_args();
  $hook = $args[0];
  if (!is_string($hook)) {
    $cache = array();
OT: I micro benchmarked { $var = arr[0]; unset($arr[0]); } vs { $var = array_shift($arr); } and the assign and unset is consistently about 10%-30% faster.
