more possible solutions:
- bind allocation of TIME_WAIT sockets to sequential/random
allocation switch
(when doing the transition to sequential port allocation, also make
possible allocation of sockets in TIME_WAIT state)
- do not (re)allocate sockets in TIME_WAIT state by default. if
number of free ports reaches certain watermark, turn on allocation of
sockets in TIME_WAIT state.
