How so? the whole idea of caching the data is so the database stops
taking the pounding.

APC (Alternitive PHP Cache) and afaik Zend Cache don't cache the
database data, they cache the execution instructions of PHP code so the
PHP intrepreter doesn't have to recompile the code every time, but if
there is a query it still queries the DB every time.  I've experienced
this first hand with APC.  At first I thought it would cache the entire
PHP output, which would include the data, not just the execution
instructions.  But I was wrong.
