Sure will do, I have an ipv4 version of the test program and a better patch.
Initial results are quite similar for resource usage. The ipv6 GC does a good
job at managing memory  resources with max_size threshold removed. I'll
include some comparison stats after I test this  extensively when I submit
the new patch.
