You know, Tom, perhaps part of the thing you have trouble
with is that you have a habit of snipping out context, 
making whatever point you're trying to make difficult for anyone else to understand.

I don't think I have to "prove" it. I'm telling you what
happens. I can't prove that the Sun is bright either. It
just is. You shouldn't get RX_OVERRUNS with a constant
traffic stream running at 60% usage, but you do. And if 
you do something in user-land, like a database lookup, it
gets worse, which also shouldn't happen. On BSD the lookup
will take a real long time, but you won't drop packets on 
the network interface. It can probably be tuned, but only Linus and Allan know how to do it most likely.
