> In UDP, we check whether a datagram socket is closed by invoking {{DatagramSocket.isClosed()}} for every message that's sent. Flight recorder showed that this creates a bit of lock contention as isClosed() is synchronized.
> SOLUTION:
> * Simply remove the check. If a socket is closed we'll catch the exception anyway and handle it.
