The new 20070129 version of udp-receiver now has a --start-timeout
option, which allows to specify a timeout, in seconds within which the
sender must send a rendez-vous packet, and then the first data packet.
If no rdv packet has been received with n seconds of starting
udp-receiver (or if the transmission hasn't started within n seconds of
sending the rdv packet), then the receiver aborts.
Once the transmission has started, the receiver continues, even if the
server becomes slow afterwards.
