Ah, so what about changing the app_server test environment to use the
same tactics you wanted to implement for your clipping test app?
This would benefit the whole app_server testing.

Sure, I guess that's best done over IRC. When do you have the time to
do this?
I don't know if I find enough time today - I have some right now, but I
don't know long that will last... (having to eat and all :-))
In any case, I could hang out in #haiku if I find the time.
Bye,
Axel.
