For one-shot notifications, use `note`, which provides `notesleep` and
`notewakeup`. Unlike traditional UNIX `sleep`/`wakeup`, `note`s are
race-free, so `notesleep` returns immediately if the `notewakeup` has
already happened. A `note` can be reset after use with `noteclear`,
which must not race with a sleep or wakeup. Like `mutex`, blocking on
a `note` blocks the M. However, there are different ways to sleep on a

		// Don't wake h.done. We need to transition to status 16 first.
	case 16:
