makes sense :)

Its not needed indeed, but trying to send multiple udp packets from a single
port in a single execution round is a common case in what I use this for, and
not easily prevented, so I buffer those and send them one at a time in the udp
port object. A typical case of this is sending log data to a syslogd on
another machine.

The same could be achieved with a 0 delay call_out of course.
