Sadly, I have basically no experience in this area -- perhaps that's why Sven's arguments make sense to me.  ;)

As Nick said earlier: the caller always blocks; by extension (to my mind, at least) putting an `await` in front of something is saying, "it's okay if other tasks run while I'm blocking on this call."

Maybe we can get there someday.
