[Zope-Coders] Signal forwarding

Sure.  So we should provide a tool.  Apache uses a socket rather than
signals for all common admin functions.  This is all hidden in the
apachectl tool.  We can do the same -- after all Zope is already
listening on a socket; even if we don't want to use HTTP, adding
another socket to the mix (e.g. a Unix domain one for security)
shouldn't be any problem.

I think it's rather perverted to think of signals as the way to
first-class citizenship... :-)
