If we add this, I'd rephrase it to something like that there are
high-level programming abstractions such as the pthread_condvar
interfaces or semaphores that are implemented using the syscall and that
are typically a better fit for normal use cases.  I'd consider only the
condvars as something like a wrapper, or targeting a similar use case.
