Just to clarify a bit, whether threads are privileged or not is
determined by whether they reside within the roottask space.
Currently, it is just the Iguana server thread.  The check in 
L4 is is_privileged_space(), currently this checks whether a given 
space is the root space.

L_timer reside within the Wombat PD.  The Wombat PD is a separate PD
from the Iguana server.

I hope this clarify things a bit and haven't made it even more
confusing.
