For guest users on every request executes query:
SELECT `uid`, `displayname` FROM `users` WHERE LOWER(`uid`) = LOWER(null)
as I see, uid can't be equal to null by design.
We always query the database backend. Even if we use a different one
(ldap for example). Now we do this everytime we try to get a user object
so caching that a user is not in the DB safes some queries on each
request then (at least 2 what I found).
