It's possible to add more Zeo Clients which will produce more available
threads. I don't want to buy more machines if the machines we have aren't
being using to capacity.

If there is a way to see that the Zeo Clients are getting more requests
than they can handle and thus queueing up requests it is probably time to
add more machines.
