net.server_epoll: Separate handling of new incoming and outgoing connections The :init method is more suited for new outgoing connections, which is why it uses the connect_timeout setting. Depending on whether a newly accepted connection is to a Direct TLS port or not, it should be handled differently, and was already. The :starttls method sets up timeouts on its own, so the one set in :init was not needed. Newly accepted plain TCP connections don't need a write timeout set, a read timeout is enough.
