Fix server shutdown
A previous fix to make close() occur later can cause socket reuse by servers to fail as previous sockets are left asynchronously open.
This change:
- adds a callback to TCP server shutdown to signal that the server is completely shutdown
- wait for that callback before destroying listeners in the server (and before destroying the server)
- handles fallout
