Which is the right behavior?
Perhaps both?
I'm novice here, but if i'm reading the man page correctly, it says:
SA_NODEFER
Do not prevent the signal from being received from within
its own signal handler.
(they also imply that SA_NOMASK is the old name for this,
which might make it clear what it's use is).
In which case blocking (masking) when it's not set is exactly what it's
supposed to do.

Yes. That's true.
But what about sa_mask? Description of SA_NODEFER and sa_mask both do not
say, that usage of sa_mask depends on SA_NODEFER.
But kernel only uses sa_mask, if SA_NODEFER isn't set.
So, I think man page and kernel are not consistent.
