One difference between this implementation and the previous one is
this busy loop. rte_pause() relaxes the cpu, but will not make the
calling thread to sleep and wait for the sync event. So here we can
spin a quite long time until the other thread is scheduled by the OS.

Yes, this is a difference. We could add a microsleep to allow for the OS to un-

schedule the current thread.

Why not use sched_yield() here?

This means, it is not portable to Windows. The function needs to be moved to OS specific files. Are there any guidelines on creating OS specific functions? Can I create in this case?
