With the proxymap one could have relatively few instances (say, 5) of it,
so the number of connections will be low as well, but that does not
directly imply low load. Correct me if I'm wrong, but AFAIK multi server
processes like the proxymap don't enforce max_use strictly. This isn't good
for the coin solution.
