AFAIK posix says that blocked signals have to be queued (at least one
of them) and that signals have to be delivered when those signals are
unblocked. I don't know if it makes sense about hardware signals, but
that's the spec.
I agree with the signal modes you proposed, but you should also
allow the user to set the 11 mode in some way. Debuggers could need that.
Bye.
