Actual behavior

The debugger breaks on an uncaught exception on the following:

1. Debug the above code with "Breakpoints: Uncaught exceptions" checked.

The problem is that sys.exit() works by raising the SystemExit exception, so this is expected behaviour. I'll consider this a feature request to have an option to ignore SystemExit.
