Sorry guys, other two (silly?) questions:
1. apart from the process callback, which callbacks need to be
RT-safe? Looking around I found a master thesis  that says: "Apart
the JackProcessCallback callback, which is called in the realtime
audio thread for obvious reasons, all other callbacks are called
asynchronously in a specialized non-realtime thread, to avoid
notifications to interfere with audio processing", is that true?
2. may the system sample rate actually change (while a client is running)?
