Interesting!  In 2.6.0 the -Z flag is documented thus:

  -Z 0 or 1

    UNIX only! This option is ignored on Windows.

    This option controls whether a management process will be created
    that restarts Zope after a shutdown or crash.
    
    If the argument to -Z is non-null (e.g. "-Z1" or "-Zyes"), a
    management process will be used.  If the argument to -Z is "-", or
    "0", (e.g. "-Z-" or "-Z0"), a management process will not be used.
    On UNIX, the default behavior is to create a separate management
    process (e.g. -Z1) if the -Z option is not specified.

    (Note: the -Z option in Zopes before Zope 2.6 used to be used to specify
    a pidfile name for the management process.  This pidfile no longer
    exists).

at least in < 2.6 it also toggled whether tracebacks were
displayed openly (debug mode) or embedded in an html comment.

What he said. :(
