I'm sure I'm not the only person who's done something like the following 
by mistake:

<?php

global $user;
// Do one thing like access $user->uid.
// Other, unrelated code.
$user = user_load(...);
// Boom!

This makes me think that standardizing on $GLOBALS would be a good 
thing. Can you link to where you found the 25% faster benchmark?
