If so, is there enough info here to update it?
The latest futex(2) or futex(4) manpage I saw doesn't mention FUTEX_REQUEUE at all. Also, any futex man page should probably SEE ALSO Ulrich's futex paper: http://people.redhat.com/drepper/futex.pdf which helps understanding how to successfully use futexes, because it is certainly not trivial.
