Yes, that is what I was getting at. Signals and interrupts are
a very old concept, and I've always thought that exceptions are
a more evolved version of the same concept. So it would make
sense to use a more versatile feature to implement a less versatile
one, if they are of similar nature.
You suggested, that I was confused about the purpose of exceptions
in Mach. Maybe I am, what is your take on this topic?
