That's a very good book, but it doesn't cover everything. Exceptions can
be thrown and caught in several dozen languages that run in UNIX-like
operating systems.

That probably varies widely by architecture, etc.

There are many, many facilities that use different methods and
techniques. See ptrace, gdb, valgrind, etc. There are so many debugging
tools available that it would be a difficult task to even summarize the
main ones.

I don't know why it would be desirable for the operating system itself
to provide this functionality. The trend is actually in the opposite
direction.
