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.

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.
