If the parent pool cleanup is called, that pool is being destroyed,
which also destroys all its children pools (for each parent's child,
apr_pool_destroy(child) is called by apr_pool_destroy(parent),

Here that's a pre_cleanup of session->pool (parent), so mplx->pool
(child) will be destroyed after, but in any case child->pool is to be
destroyed, you can't avoid that.

Yes, we only need to cleanups things (or take actions) that are not
cleaned implicitely by the pool itself.
