As Pieter said it depends on whether there is still in-flight data or not.
Also it's different for client and server. So have fun finding all the
relevant combinations for SO_LINGER and (on Linux) the usefulness of
net.ipv4.tcp_tw_recycle or net.ipv4.tcp_tw_reuse (for influencing the
TIME_WAIT state). Or whether they work correctly on any given kernel.
good luck :)
