I'd like to propose that we pull libck into our tree and use it to replace some of our stuff like the freelist, ink_atomic_list and hash tables.
http://concurrencykit.org/ Right now there are not enough distro's to make just linking against system libs feasible, but I'd like to set it up in such a way (configure time option) so that we can encourage distro's to add a libck package in the future.
