What happens when a socket in FIN_WAIT2 is close()d, or a process exits

Suppose the process is able to exit but the socket lingers.  In that
case will the lingering socket defeat resource controls?
*This* is exactly the kind of issue I was talking about.  Thanks for
making it clearer than I was able to do.
Note: that's the only issue I can imagine.  The other timers' being
configurable obviously create no such problems.

Ok, I confess that the plethora of TCP related timer values are not something I have good familiarity with -- my concern was that resources associated with a socket would outlive the handle by which they were accounted (the associated open file).
