Good!  I've checked that change in (both in Zope and Zope3), so you
shouldn't see this again.  Thanks for pointing it out!

It's a different issue and one I'm incompetent to address.  CLIENT_HOME
appears to be one of those names that gets inserted into Python's
__builtin__ namespace as a magical side-effect of importing something; in
this case, apparently as a side-effect of z2.py's

if Zpid and not READ_ONLY:
    import zdaemon, App.FindHomes, posix
                    ^^^^^^^^^^^^^ this one
    sys.ZMANAGED=1

But the code beyond that references CLIENT_HOME regardless of whether the
import of App.FindHomes is done.  I trust we're equally lost now <0.5 wink>.
