Also, I would like to forward that on to Mark and see what he says.
The motivation is the entire musician community who wants to not leave
Ubuntu... It's not just a request from you, but really a request made
on behalf of all potential Ubuntu musicians.

I don't know check, exactly. Is it by
version? Debian Sid appears to
have libc6 (2.3.5-12) according to the package list. I'm running
Breezy here, 2.3.2.

OK here is my message to the Ubuntu developers and their response.
Briefly, if we can submit the needed patches by the 26th, then Dapper
will support the new rlimits. On Thu, Feb 02, 2006 at 04:48:20PM -0500, Lee Revell

The new RLIMIT_RTPRIO was introduced in kernel
2.6.12 to selectively
allow non-root processes to run tasks with realtime priority. This is
essential if we ever want reliable multimedia performance without
forcing users to run as root.
Supporting this new rlimit requires some changes to glibc, bash, and
PAM. It was added to glibc 6 months ago:
http://sourceware.org/ml/libc-hacker/2005-06/msg00005.html
Presumably Dapper will ship with a post 2.6.12 kernel - so will Dapper
ship with full userspace support for this new rlimit?
I checked the current glibc sources and these new RLIMITs are not yet
supported...
Dapper feature freeze begins 2006-02-23. If you submit the appropriate
non-invasive patches in time for them to be merged before that date, I
see no reason not to include them. However, as yet, there is no motive
to push ahead of our upstreams on this point except for your request.
