Need an explanation of APR::Pool and it"s use in mod_perl

Hello everyone,

I've been looking over the APR::Pool because some pools gets passed to =
some of my handlers and I was wondering how I could use it to good =
effect managing my memory better.
There are great instructions on the API for it, but no real explanation =
as to how to use the pool (at least not in the APR::Pool docs.)

I was wondering if anyone could explain how to use memory pools to =
manage memory, or point out some examples I might have missed.

I'm not looking for what's already in the doc, i.e. I already understand =
what is mean by the life cycle of the pool, destroy vs. clear, etc. I'm =
looking for more of an example of how to use the pool with my memory, =
i.e. do I have to create my data structures in the pool somehow, or is =
it taken care of automagically somehow that isn't obvious? It seems =
pretty low level, is it something I should avoid, via higher level =
modules or something like that?

Thank you,
