If nothing is received httpd won't even notice on some platforms due
to BSD accept filters or TCP_DEFER_ACCEPT on Linux. This means a 408 cannot
be logged here in general. But I admit that even on those systems there might
be cases where the socket was passed to httpd and no 400 is logged.
On this case it might make sense to adjust the logging behaviour accordingly.
