[Zope] Zope 2.7.0 zopectl problems (bug?) and questions

[Chris McDonough]

Apparently zopectl doesn't work properly under OS X or Solaris.

Starting Zope under zopectl (if it worked properly) would cause it to
auto-restart.

You distinguise the Zope process in the ps listing by looking for a
process that runs python.
