Each mod_python child process is its own ZEO client.

Not except for the ZEO storage server.  Apache is responsible for
managing the lifetime of its child processes (which would likely persist
across some number of requests).

This is the major benefit of the approach:  sysadmins don't have to
monitor / manage a separate daemon.  Another potential benefit is that
each child behaves as a single-threaded appserver, with no
GIL-contention issues.  A potential downside is that the child processes
will not be able to reused the local ZEO client cache.
