The client can't connect, but keeps trying.  The reason for this behavior
is to prevent clients from dieing when a server is temporarily down,
misconfigured, or unreachable.

Try enabling logging:

import logging
logging.basicConfig(level='INFO')

Then you should be able to see the error.

Are the client and server running the same versions of ZEO?

ZEO 5 clients can talk to ZEO 3, 4, or 5 servers, but ZEO 5 servers can
only talk to ZEO 5 clients.
