[KERNEL] Slow down with RTT measurements after 30 seconds
Right after connecting, all servers will be polled every 4 seconds for 30 seconds,
so we get 7 data points per alt-server. If no better server is found during
this time, further RTT measurements will be done every 22 seconds, to put
less load on the network in the long run.
