Multiple netgraph threads

Hi.
I have implemented a patch (for the HEAD) making netgraph to use several own threads for event queues processing instead of using single swinet. It should significantly improve netgraph SMP scalability on complicated workloads that require queueing by implementation (PPTP/L2TP) or stack size limitations. It works perfectly on my UP system, showing results close to original or even a bit better. I have no real SMP test server to measure real scalability, but test on HTT CPU works fine, utilizing both virtual cores at the predictable level.
Reviews and feedbacks are welcome.
