We already have memory lock down. We already have real time
scheduling. We even have a spare bit in the standard signal
vector.
And, yes, I do believe that a broadcast SIGDANGER with a default
behaviour of ignore is a useful start. Ok, hardly anything uses
it at the moment - but then if it existed perhaps things might
change? :-)
