The PEP[1] notes the following about 'zdaemon':

 The zdaemon tool [zdaemon] was written for the Zope project. Like
 [slack-daemon], it differs from this specification because it is used
 to run another program as a daemon process.

In particular, that is what makes the 'zopectl' / 'zeoctl' bit feasible;
 the 'runzope' / 'runzeo' commands get run in a daemonized environment.
 The "controller" process has a different lifetime than the actual
daemon, with the two communicating over a private socket.

For the appserver, I imagine that we will move to a WSGI-based
deployment model, leaving any Zope-specific server implementation
behing.  If you wanted to experiment with Ben's library, I would
therefore focus on the ZEO server.
