The control script is just an extended form of zdaemon.  It doesn't  
do anything but invoke the application scripts.  It doesn't need any  
of the application eggs to do it's work.

We could pointlessly include extra eggs in the control script's path.

The fact that the control script doesn't actually run any application  
code and therefore doesn't need any application eggs is inherent in  
the way zdaemon works.  If it wasn't for the extensions to support  
the run and debug verbs, the control script would be a simple zdaemon  
wrapper.
