More important here is realization that eventfd is a mutex/semaphore

Well it is a generic event reporting interface (for example, aio uses it).
Davide, I think it's a valid point. For example, what read on eventfd
does (zero a counter and return) is not like any semaphore I saw.
It is similar to Win32 events (which can be used like contorted mutexes
to sync two processes).
