The async iterator returned by
asAsyncfor a concur iterable only tracked a single pending waiter, so callingnext()again before the previous call settled overwrote it and the earlier promise never resolved (e.g.Promise.all([it.next(), it.next()])hangs). This shares the pending promise between waiters and has eachnext()loop until a result is available, so concurrent calls resolve in order. Added a property test that callsnext()once more than the number of values, all at once.
