The usespace clients could leave "hints" (for example in a file) that
a cell has a bad DB server and then future userspace clients could do
something "intelligent" with the hints.

Another more agressive way would be to contact more than one db server
at a time, for example pick two at random and use the info from the one 
that answers first.
