Just a nit to pick here. In Linux, the difference between forking and
spawning a new thread is almost nothing. Definitely less than a factor of
2, and most assuredly less than the quoted factor of 10 here.
The fact that windows has a heavy process / lightweight thread design
means little to me, since I'll likely never deploy a production postgresql
server on it that needs to handle any serious load.
