+ *    Keep a thread around to timeout alive connections
+ *    even if no new requests are coming in.
+ *
+ *    Revision 1.214  2008/12/20 14:53:55  fabiankeil
+ *    Add config option socket-timeout to control the time
+ *    Privoxy waits for data to arrive on a socket. Useful
+ *    in case of stale ssh tunnels or when fuzz-testing.
+ *
  *    Revision 1.213  2008/12/15 18:45:51  fabiankeil
  *    When logging crunches, log the whole URL, so one can easily
  *    differentiate between vanilla HTTP and CONNECT requests.
