There are two issues with the code that I found and I have everything
working now. It is not enough to test with the test program (which
works); for example as I mentioned before, booting with a kernel
that has all your patches fails on sshd (you can't login remotely)
and an interrupted make does not work properly. If you want I can
show you what's wrong with the changes, but I think it is better
if you find the problems yourself. The idea here is to make sure
that the code works exactly like before in the absense of real-time
signals, which is not the case currently. Both bugs are in kern_sig.c.
One of them is the critical one that breaks signal delivery, the other
is more of a clarification of what happens when we want to maintain
the pending signal mask.
