In select_trigger.py, the non-posix version of the trigger class binds a socket to a port on the address 127.9.9.9. Can anyone explain the significance of using this address, rather than 127.0.0.1 ?

No significance. Just Sam's personal style I guess. It seriously reduced the chances of select_trigger binding to a port that something else wants to use, since it's such an odd address. It means 'localhost' just as much as the more conventional form. The TCP/IP spec says you computer can have any number of localhost addresses in the 127.0.0.0/255.0.0.0 block (or 127.0.0.0/24 for the more modern notation). -Michel
