.NET exceptions don't travel along PInvoke boundaries. The entire app just SIG quits.

We should try{}catch(Exception ex){} all .NET callbacks that are passed to native world, write the exceptions details to stdout, and then rethrow.

Even better yet, our callbacks should support an error return code. That way, native code can handle it properly.
