ZCacheable_invalidate()?

Granted that would be a limiting factor if you need to cache
a few GB worth of portlet output.
Otherwise, RAM is dirt cheap compared to the time and cost of setting up
Squid on a separate box.  (If Squid is on the same box, you probably need
to buy more RAM anyway.)

"Handle" how?
I routinely cache scripts that return arbitrary python
objects such as dictionaries.  What exactly is the problem?
