I got a better one for you, what happens if someone puts System.exit() into
their servlet? ;-)
In both cases, the JVM stops. You must write a little application to watch
things and restart the JVM if it dies.
> 3) Are all other zones in the running in the servlet engine unaffected?
Yes.
> 4) Does it bring down the entire servlet engine?
The "servlet engine" is running in the JVM. If the JVM dies, the engine
dies.

It is not directly in the 2.0 spec. It was Stefano and Pier's idea to solve
the problem.

Just memory and cpu restraints.
