FWIW, the origin of this is checkin
4d9bc79cd28b779610d9590b3a96a28a0f64a25a (2.6.18-rc1), which somewhat
unhelpfully states "Make sure is_compat_task works early". It doesn't
specify what the failure is if is_compat_task doesn't work early. On
the other hand, it sure as heck seems better to set it and not need it
than the other way around.
