Chris, I did comment on it, see
1105222442.24592.126.camel@krustophenia.net from around 5:15 on
Saturday.

from the above message:

Eh, PAM is a perfectly fine solution. Documentation is lacking, but
it's easy to find examples. On my system /etc/security/limits.conf has
this sample config, commented out:

#<domain> <type> <item> <value>
#

#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0

So add your audio users (or cdrecord users, or whoever) to group
realtime and add:

realtime hard memlock 100000
realtime soft prio 100

Problem solved.
