The goal of this project is to improve the way the processing of incoming packets is handled. Instead of having a set of active workqueue lwps waiting to service sockets, the kernel should use the lwp that is blocked on the socket to service the workitem. It is not productive being blocked and it has an interest in getting that workitem done, and maybe we can directly copy that data to user's address and avoid queuing in the socket at all.
