Where, sa_mask is _ignored_ if NODEFER is set. (I now have woken up!).
The attached program shows that the sa_mask is indeed ignored when
SA_NODEFER is set.

Now the real question is... Is this a bug?

That's not correct w.r.t. SUSv3.  sa_mask should be always used and
SA_NODEFER is just whether or not to add that signal in.

SA_NODEFER
    [XSI] If set and sig is caught, sig shall not be added to the thread's
    signal mask on entry to the signal handler unless it is included in
    sa_mask. Otherwise, sig shall always be added to the thread's signal
    mask on entry to the signal handler.

Brodo, is this what you mean?

thanks,

Yes. That's the difference between kernel and man page, that I've found.
I like the patch, at least the version Steven has sent. But at the end,
others have to decide if kernel or man page should be changed.

BTW: would you please call me Bodo? :-)
