Postgresql takes a similar (multi process) approach to achieving stability
as apache.

see pg 4 of http://developer.postgresql.org/pdf/transactions.pdf

Think shared memory caching behind the Zope worker processes ;-)

And web server / proxy shared memory caching in front of the Zope worker
processes.

Of course, for stability, there is also the possibility of doing a OpenBSD
style audit of the entire Zope (and possibly python) code base to make
the code as close to perfect (and therefore stable) as the OpenBSD OS
  is ;-)   Volunteers?
