Hi Willy, I haven't managed to find the patch, I grep'ed LKML using a bunch of search terms via the google group linux.kernel. Then I tried a bunch of different search strings in google prefixed with `site:kernel.org`. All to no avail. I have an idea how to fix it without making life less convenient for developers *or* for users, I know we don't discuss changes without a patch so I'll hack it up. I'm sure your solution contains things I don't understand yet (read: the cgroups bit) so I'd love to bring your patch back to life but am happy to work on another solution as well in the name of education. thanks, Tobin.
