FUTEX_WAIT_BITSET and FUTEX_WAKE_BITSET allow the user to specify a bitmask which limits the woken tasks to those which specified the same bitset...
I still cannot see the difference in these function names (but its been a very long day)...

WAIT vs. WAKE. One puts the task to sleep and sets the bitset by which it
can be woken, the other does the wake with a matching bitset. I believe I had to look at these a couple times myself even while writing the article!
