Comment:

 The problem was commit {{{8d59ddf3c}}}. Our code now does:
 {{{
     newconn->port = port;
     newconn->address = tor_addr_to_str_dup(&addr);

 [...]

     if (new_type == CONN_TYPE_AP && conn->socket_family == AF_UNIX) {
       newconn->port = 0;
       newconn->address = tor_strdup(conn->address);
       log_info(LD_NET, "New SOCKS AF_UNIX connection opened");
     }
 }}}

 So basically, we leak an 'address' string every time we get a unix domain
 socket socks request.
