You're right Kaj, the file itself says it: 'provided by the jackd
package'. So it's not a Raspbian default. How could I miss that while
checking and tweaking the file a dozen times.

I wonder why the file sets real time priority 95, while official
jackaudio documentation
(http://jackaudio.org/faq/linux_rt_config.html) recommends level 99.
If level 95 is Debian tradition, it would be best for pd to comply
with that level.
