Udp is a bounded transport and does not need to be thread-safe.

Please use text, not images. Images are much harder to read. Thanks.

We don't use the issue tracker for questions. If you want to ask a question, you will get better and faster answers using a forum. See https://golang.org/wiki/Questions.

We lock the FD to ensure that nothing else changes it during the write operation. UDP sockets don't need to be thread safe, but the FD structure is handling other things as well, notably the interaction with the runtime poller.
