Instead of "Hotmail doesn't > work!" it becomes "Hrm... Hotmail is fscking slow, but Yahoo is fine. I'll > use Yahoo". A few million of those, and suddenly Hotmail isn't so hot...

Ignoring valid TCP RST frames is unacceptable and Linux will not do that as long as I am maintaining it. Later, David S.
