I haven't had the chance to read Adam's document yet.

I disagree with your notion that a single Network Process doesn't much efficiency to be gained.  In a world with multiple web content processes it is important to have a single coordinator for network i/o so the systems connection and any given host isn't hammered.

That said, the work we've already done on the WebKit2 Network Process assumes support for multiple Network Processes at some stage.  Actually making use of them can be rolled in once the fundamentals in place.
