If we go ahead with this, I'd like to adapt FUTEX_WAIT_REQUEUE_PI to use 
this as well, as it faces all the same races related to the calling task 
getting to sleep in the kernel before a wake call (FUTEX_CMP_REQUEUE_PI 
in this case) as futex_wait does. FUTEX_SET_WAIT_REQUEUE_PI is 
ridiculously long... but it is what it is I guess :-)
