In upcoming revisions of Zope, the pidfile name might be speficiable via
a config file and Zope will more likely be controlled by a process named
"zctl" (like apachectl) than by start and stop scripts... zctl will be
able to parse the config file so it could pretty easily find out where
the pidfile was.

Then again, I'm not sure about the utility of changing the pidfile name
if you can change CLIENT_HOME anyway, so maybe it shouldn't be
specifiable.  Would you ever want to change the location of a pid file
and *not* change it to a place where the associated instance's
filestorage files were?

OK, if I get around to it, I'll give it a go... thanks for thinking
about this (and for catching the Shuttle-crasher bug in zdaemon). ;-)
