  • Use a BinaryHeap for Exchange::waiting.
  • Wrap GetConn wakers inside the new QueuedWaker.
  • Use the new QueueId which is an atomic u64 counter
    to prioritize the enqueued and re-enqueued wakers.

The AtomicU64 may theoretically wrap around, though should
not matter in practice. Should be documented.

Closes #212
