Review Comment:
Now I finally understand, I did not read documentation of sigwait()
carecully enough.
> The function accepts the signal (removes it from the pending list of
signals), and returns the signal number in sig.
So the only thing that needs to be done is to fix the system call behavior,
when masked == 0. The signal action is not currently performed. I'll provide a
patch in a moment.
