 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.
