This is strange - iburst sends its polls at 2 second intervals, and with
a good drift file will sync the clock in about 11 seconds' time.

Dropping minpoll from 6 to 4 should only help if the initial conditions
are "off" enough that the initial iburst volley didn't match up with
things like the stored drift value.
