What if you use your memory allocation functions on the parts of your
application and let libwww use its own functions? This is what we do
in Amaya.

You could then use the "persistent" pool for the requests and free everything
when the request ends. You can detect this condition either thru a
terminate_handler or by an error return from the function you initially
call (e.g., HTLoad ()) from your application.
