Hey! Why don't we shove the networking engine in kernel-space! Then we
can stop all these other pesky processes from pre-empting us and stuff.

I'm not sure if this is a really important issue right now. As many
people have noted, premature optimization is the source of all evil. 
What we _need_ is a good api to the networking code, so that the 
underlying code can be optimized later. Actually optimizing the way it works
should be dealt with when you need to deal with it. After all, it may work out
that the control code behind it all ends up needing 1/4 of a cpu/thread, at 
which point this problem morphs into a completely different one. 
Someone might release a nice lightweight threads architecture in 4 months
meaning the point is unimportant.
