When a PuSH hub is operational, dfrn-poll clients prefer to receive their information through the PuSH channel.
They will fall back on a daily poll in case the hub has delivery issues (this is quite common when using the default Google reference hub).
If there is no specified hub or hubs, DFRN clients will poll at a configurable (per-contact) rate at up to 5-minute intervals.
