[Moshe Weitzman]

  Is it possible to find out the order of hooks calls when a page is
> called? Is there a rule or function that determines this? Is it 
> immutable and dependable information that can used in the creation of a 
> module?

in HEAD Drupal, this order can be customized via the system table. see 
the weight column. module_list() uses that ordering for its hook 
invocations.
