Yeah,. its what clued Mike in to there being a problem.

I agreed, I've just been unable to come up with anything sane.
The best I could come up with is renaming
{set,clear,test}_need_resched() to {}_tif_need_resched(), so we then end
up with test_tif_need_resched(), which is slightly more different from
need_resched().
Ideas?
