Currently, for each `Disconnect()` call, we spawn a coroutine, but every one of them is just usesless, except the first one. However, since all `Disconnect()` usages share the same asio strand and cannot interfere with each other, spawning another coroutine within `Disconnect()` isn't even necessary. When a coroutine calls `Disconnect()` now, it will immediately initiate an async shutdown of the socket, potentially causing the coroutine to yield and allowing the others to resume. Therefore, the `m_ShuttingDown` flag is still required by the coroutines to be checked regularly.
