No actually it isnt. I ripped out a lot of the old code. All other stuff
is easily handled by the cache code anyway.

ZSQL Methods and all that stuff is horribly old and full of calamities.
Apart from the cache management nightmare, there is also a lot of
ZMI stuff really wrong. You dont see the right encoding because
the test pages ignore it, you have a "pretty formatter" for
column names - hiding their real name and you always have to wonder
the name of the variable you get in the result set.

("fOO_bar" becomes "FOO bar" for example)

and so on :-)

I think I just upload what I have so you can have
a look at it :-)
