It's less simple than I thought at first, but simpler than I thought at second. The asynchronicity makes things a little harder to deal with (you essentially need to use the logger for all the messages you want to output, otherwise it can become gibberish), but is also a nice feature to let the main program run smoothly. Their parameterizability is also very nice, as it allows to completely shut up one thread while letting the other shout, even though they use the same procedures. I'm glad I took the step from `displayln' ;) Laurent
