Yes, one time per observer (or more if the observer decides to). 
Actually, I think Unicorn also fetches it one time, to see if the 
document can be reached to avoid calling many observers if that's not 

That may seem a lot, but I think that's the only way unless we used some 
complicated caching mechanism on Unicorn's side (which could lead to a 
loss of information btw).
