The rub is that the timer in many implementations of SO_LINGER
simply doesn't exist. So even if you set a timeout of 10 minutes
or so, this value is ignored and the process will keep trying to
send the data forever. Most BSD 4.3-based stacks have this
failing... SysV4 supposedly has the timer fixed, but just a
plain old bogus SO_LINGER setup.

I'm guessing the IRIX 5.3 has a non-functioning SO_LINGER
timer... it's of that time frame. Also sounds like it doesn't
have a FIN_WAIT_2 timeout either :/
