   The BGL work on the network stack is very close.  There are two 
queueing mechanisms that need to be locked up (sockbufs and IPQ), 
after which we will basically be able to turn off the big giant lock 
in the network protocol threads.  IPQ should be straightforward.  The 
sockbufs are more of an issue but it should be possible to separate 
the reader and writer sides of each sockbuf to avoid contention 
between userland and the protocol stack.
and we need to lock down pfil or start parallelizing them (probably 
only pf, with newest version imported)
