rlimits does not work

I'm messing around with jackd, and it and rlimits are giving me an extremely hard time. /etc/pam.d/gdm is set up right, so I know that the stuff in /etc/security/limits.conf should be obeyed:

@audio          -       rtprio          90
@audio          -       nice            -5
@audio          -       memlock         500000

but whenever I try to run an application using jackd in realtime-as-user mode, it tells me that it can't lock down the memory for realtime.

Furthermore, jackd as user - even *without* realtime - gives me nonstop xrun messages ("of at least 1212617444032.512 msecs", which I find hard to believe) and makes my sound stutter horribly. As root, this doesn't happen, but running jackd as root is not secure and I would rather not do it.

I filed a bug on the rlimits thing a while ago, the devs are too busy to bother with it... can someone please tell me what the heck is going on?
