Most of the stacks I'm familiar with give an established connection at least
that long; perhaps more like 5+ minutes. When there's a user waiting, they often
decide to give up before TCP does..

regular basis. The thing I keep surprising myself with is how many
differently-broken networks show improved performance when you shrink
the tcp window.
