Whole-page caching gives you lots of "bang-for-buck", because it
allows Squid to take over most of the page-serving burden (90-95%
on the system we know mest) from Zope.

I think that PythonScripts which need caching should be written
specially to take advantage of the CacheManager architecture
(perhaps there is another tool which would help for this kind of
caching).  I don't think being able to signal automagic caching
on the FSPythonScript object feels like the Right Thing (tm).
