I'm violating my own dictum. I'm replying one more time.

Demon Internet in the U.K. was running NetBSD for its routers at the
big exchange point in London for a while as I recall. Lets assume that 
each of those machines was handling fourty or fifty thousand
simultaneous TCP connections transiting through. Thats, what, fifty
megabytes of state? Plus all the CPU for processing each packet? Plus
a giant cache miss for every single packet going by?

Even on modest networks we're talking about a lot of connections.

I imagine that many of UUNets big routers handle hundreds of thousands 
of simultaneous connections passing through them at "the same time".
