I was actually suggesting that it was a ZSI trick, as it certainly is
not a mod_python trick (except when using publisher). What I was
suggesting was that ZSI seems to be doing some introspection of
MyHandler, and *it* might be choosing to treat methods prepended with an
underscore as private. But then, I know absolutely nothing about ZSI. :)
