[development] global $user unavaialable?

[Moshe Weitzman]

that snippit tests if the user is logged in, not if $user is
populated. you could have a full anonymous $user object.

the basic loading of a $user gets triggerred by session_start() but if
you have to call that on your own you are way off the beaten path in
Drupal and really need to grok whats happenning step by step in order
to assure security and code sanity. that gives a basic $user object.
If you need it call, you might have to call user_load() yourself.
