Then you're correct, vendors rarely turn this on :) I do sometimes if I'm trying to chase down something particularly difficult, and it usually gets me a bunch of mail from users asking why 'everything got all slow', so it's a last-resort option rather than a 'on all the time' option.
Yeah, maybe it is a last resort option for users, but at least for internal testing it helps. We regularly run such debug kernel through testing cycle and it catches some races from time to time.
