repeated polling is counter productive. for the 6 times the high-prio
push was needed in the last year, its a waste to destroy mirror cache's
every 10 min through the entire year.

having dedicated nodes to just push rsync targets is also bad - since
those machines then dont deliver any user facing service ( or bandwdith
) for most of the time.
