What is the current wisdom on SA_INTERRUPT?
A comment in signal.h about it says "dummy -- ignored". Elsewhere it says that "SA_INTERRUPT is a no-op left for historical reasons".
That certainly doesn't seem to be the case in irq.c. It appears to be used like this: if SA_INTERRUPT isn't set, enable interrupts during interrupt handling.
So what is this flag for? How, when, and why should it be used?
Thanks.
Regards, Brad
