APR pools allocate but do not automatically deallocate.  They hang onto
the memory they have and reuse it later if possible.  If you want to set a
limit on the amount the pools' underlying allocator will hang onto, use
apr_allocator_create(), call apr_allocator_set_max_free() or whatever it's
called, and then use apr_pool_create_ex() to create the pool with that
"limited" allocator.

Have a look at the prefork or worker MPMs from httpd for an example.
