This seems fundamentally racy, no?  In particular, the fact that a new 
load can start (and maybe finish?) between the loaded() call and the 
time when the promise notifies its consumers is a bit worrying.

I agree that we need something better than the current easy-to-miss load 
event setup here, though....
