Yes. Either one for all the tests or one per test assembly, depending
on the settings you use.

NUnit has always run the tests in a separate AppDomain. That's
how the test assembly is able to have its own application base
and configuration. There are some issues with how mono does
appdomains, but our tests all run successfully on Mono - I
test on Windows and Ubuntu myself.

Is the exception you are seeing one that has slipped past NUnit
and is being handled by the environment? Can you run a simple
test?
