After starting Zope all its caches are empty and rendering the first one
or two pages from a Plone site can easily take 30-60 seconds during which
every is blocked. Once the caches are warm this drops to 1-2 seconds. So
what we want to do is start Zope and first run a few requests through it
to warm up its caches. That prevents thundering hurd problems where
requests are piling up while Zope is still filling its cache.
