Okay, maybe - but I just saw that artsdsp xmms segfaults here (Debian
unstable AMD64) in gsl_init -> gsl_thread_self, so, to say the least,
its not always working perfectly. Xmms did work some day.

Well, artsdsp will not fail on the first open, so I guess Kino will be
keeping the first one. Generally, you can use artsdsp -v to see which
syscalls get intercepted; you can use strace on the original binary to
see which syscalls the application normally makes.

If select/poll is in there, and the application depends on its
correctness, then probably you'd need to add some code to artsdsp to
make it work.

   Cu... Stefan
