The vast majority of ups and downs are actually mutex related not semaphore related, so by majority share, up/down perhaps ought to be repurposed to mutexes: they _are_ the preeminent uses. >From my modified tree, I see: semaphore up down down_in down_try Counting 41 59 1 0 Mutex 4405 2824 362 107 > The old API is still very useful for some applications that want > counting semaphores. Whilst that is true, they're in a small minority, and it'd be easier to change them.
