I had looked for such option in the manpage and --help and couldn't find
it.  Could it be documented please?  Also, the

“JACK is running in realtime mode, but you are not allowed to use realtime scheduling.
Please check your /etc/security/limits.conf for the following lines
and correct/add them:

  @audio          -       rtprio          100
  @audio          -       nice            -10

After applying these changes, please re-login in order for them to take effect.

You don't appear to have a sane system configuration. It is very likely that you
encounter xruns. Please apply all the above mentioned changes and start jack again!”

warning should also suggest using -L if realtime scheduling is not
desired.  Yes I know I'll get cracks etc. but I don't care and prefer to
avoid realtime priorities :)
