I have be on/off working on an updated futex implementation written by Taylor, with the intent of making it a native call (in order to improve or own semaphore and mutex implementations). You are correct in that the current implementation is lacking.
I will try to focus on finishing up the new implementation soon. But even the stuff written by Taylor is a little lacking compared to what modern Linux uses futexes for, so some additional work is going to be required.
