btw. I am not terribly concerned about not being able to saturate a
gigabit network. In my mental model the local cache is large enough to
cache everything I care about, the period prefetching (hoarding) will
pull in anything that may have changed on the servers and the
write-disconnected operation will send any local changes back to the
servers in the background.
