TIME_WAIT is a TCP state, and any socket is expected to be in
this state on a side which does an active close for 2 * MSL
seconds after a connection is closed.

Reducing keepalive_timeout isn't expected to reduce number of
sockets in a TIME_WAIT state. On the contrary, it may cause more
connections to be established and then closed, resulting in more
sockets in TIME_WAIT state.
