net.server_epoll: Immediately attempt to read from newly accepted connections This may speed up client-first protocols (e.g. XMPP, HTTP and TLS) when the first client data already arrived by the time we accept() it. If LuaSocket supported TCP_DEFER_ACCEPT we could use that to further increase the chance that there's already data to handle. In case no data has arrived, no harm should be done, :onreadable would simply set the read timeout and we'll get back to it once there is something to handle.
