Maybe. Depends on what JACK clients you run (they all get mlocked).
Ardour takes up quite a lot of space. If you're willing to grant the
max priority (100), your system is probably a dedicated audio
workstation, so you might just as well make memlock "unlimited".

There is also the -m (--no-mlock) JACK option that disables memory
locking even with the -R (--realtime) option.
