Hmm, I'm almost sure this is wrong.
It makes race condition in threaded servers.
shutdown is blocking call.
Any particular reason why you changed that?
The shutdown is done on the socket belonging to the endpoint, so it is
not in concurrent use (the endpoint got it's socket for private usage
before we called this function).
So synchronization should not be necessary for the shutdown and thus the
blocking nature of the shutdown is not evil.
In fact the only reason I moved it to the front was:
- I think it is allowed to move it outside of the lock
- If we then move it in front, we don't need to first save the socket to
a temporary variable only to destroy it at the end. We can destroy directly.
Anything wrong with this reasoning?
