No, I missed the mac_priority. It looks like that's the perfect solution! I
just tried it and it works - although the manpage says it's from Rel. 14.0, and
I have 13.2.

With that method jackd brings only one thread into rtprio - and it is NOT the
one as above.

I'm currently running it without rtprio, to see if the "buffer balancing"
reappears - but that may simply have been caused by a week-old firefox filling
up ressources or whatever else. After starting and stopping jackd a couple of
times my desktop did finally crash, and I couldn't investigate further - maybe
it was already corrupted in one way or another.
And while I do analyze server crashes, I don't care much about desktops failing
occasionally - it's mostly not reproducible, and there is too much random
activity happening behind the curtain, even without DBUS.
Anyway this is not a DAW, just a little add-on to finally replace my failing
stereo&tapedeck.

So yes, I'd recommend remove the rtprio hack.
