	This timeout occurs at the protocol level, and for netinet, for
  instance, you should look at tcp_keepidle (available as a sysctl) and
  tcp_maxidle.
	For TCP, the procedure that you are probably looking for would be
  tcp_timer_2msl() -- it takes care of checking whether ETIMEDOUT should be
  returned in the case of a timeout (as opposed to waiting for a FIN
  forever).

  Have fun,
  Bosko.
