I don't suppose we already have NPTL and FUTEX, as same are used by
libc, anyway. If we want perfect performance and good (Posix-like)
behavior of the threaded applications, but no libc binding, NPTL and
FUTEX API calls need to be done instead of old-style clone() and
interprocess semaphores. Especially FUTEX  is tricky. (read "Futexes are
tricky" by U. Drepper: http://people.redhat.com/drepper/futex.pdf)
