Well... I know, it is very easy to blame somebody else's patch, and probably
my taste is not good...
But honestly, I personally think this approach is a horror, and any alternative
is better :)
I'd rather change dequeue_signal() so that it takes "struct sigqueue *"
parameter instead of "siginfo_t *", or add a new "int *flags".
OK, this doesn't work anyway, we should do something different. Perhaps
just do all checks on sender's side.
It is a bit strange that this patch is 3/15, and the rest bits in 11/15,
not very convenient for the review.
