I seem to remember correctly. Following the "browse source code" link
from https://tracker.debian.org/pkg/jackd2 , then opening the "debian"
folder, apart from the post install scripts there's also this:

"Enable realtime process priority?
 If you want to run jackd with realtime priorities, the user starting
 jackd needs realtime permissions. Accept this option to create the
 file /etc/security/limits.d/audio.conf, granting realtime
 priority and memlock privileges to the audio group.
 .
 Running jackd with realtime priority minimizes latency, but
 may lead to complete system lock-ups by requesting
 all the available physical system memory, which is unacceptable in
 multi-user environments."
