You want to execute "ulimit -a". You should not need it, since 2.6.12 the standard
kernel contains the
realtime rlimits. If your distro ships a 2.6.12 kernel, they need to
update their PAM and bash packages to support this feature
(check /etc/security/limits.conf and the output of ulimit for any
mention of real time priority). Otherwise it's a bug.
I'm running kubuntu/breezy with their 2.6.12-3-amd64-generic kernel
and not sure what else to actually check for. My
/etc/security/limits.conf is totally commented out and ulimit returns
"unlimited".

Great, thanks David, my output looks similar to this and certainly no

Surely there is a URL to a doc somewhere explaining how to apply the
realtime settings to a kernel and where the PAM patch is and how to
set it up ?
Has anyone got an example of how to configure /etc/security/limits.conf
once the PAM patch is applied ?

Please file a bug report with your distro and ask them to update their
PAM packages with this patch.

I'm adding support for this to bash right now. Unfortunately it
requires glibc changes too (/usr/include/sys/resource.h). I'll post a
patch when I have it.
