>i wonder if godaddy's tcp does not reset in that case - anyone care to verify?

i cannot think of a sensible reason it should do that: it seems more work for the receiver,
to run an extra timer to time the probes. even when the probes are based on the retransmission
timer they could easily occur on the order of tens or hundreds of microseconds on some networks.
you don't want something as big as 5 seconds because the window-opening packet might
have been zapped, and who wants 5 second delays because of that?
it's not for nothing that rfc793 and rfc1122 say what they do.
