It has been in use in a similar form on our systems for some time. There is a small change needed for glibc, and I will send that patch to the glibc people if/when this gets pulled. Unlike prior versions of this patch, I have changed qsort() to a simple non-recursive sort. Several people indicated that this change would solve their objections. Lastly, this does not fixup all the architectures. I have other patchsets for that, which need to be reviewed by arch maintainers.

We now have a per-task, dynamic array of groups, which is kept sorted and refcounted. This ChangeSet incorporates all the core functionality. but does not fixup all the incorrect usages of groups. That is in a seperate ChangeSet.
