        In commercial Unix systems, this kind of parameters, such as 
        tcp_timewait in AIX and tcp_time_wait_interval in HP-UX, have 
        already been available. Their implementations allow users to tune 
        how long they keep TCP connection as TIME-WAIT state on the 
        millisecond time scale."

This statement only makes me happy that these systems are not as
widely deployed as Linux is.

Furthermore, the mere existence of a facility in another system
is never an argument for why we should have it too.  Often it's
instead a huge reason for us not to add it.

Without appropriate confirmation that an early time-wait reuse is
valid, decreasing this interval can only be dangerous.
