Done. I provided a test program that shows how it works in each environment.


The new behavior makes sense for the average program: if an exception isn't
handled, it should be terminated. For programs that need to do something
before it terminates, the new behavior is OK as well. It is a problem for a
program like NUnit that wants to report an error and then continue to run
other tests. It would be a problem for any program that used the
UnhandledExceptionHandler to turn
off a facility (like an addin) and continue to run in a degraded mode.

Anyway, it's documented as a difference. If it's not changed, maybe it
should go into a short list of "Things we deliberately do differently."
