`dotnet fixie`'s return code is no longer the sum of each individual test assembly's return code, because return codes cannot be reliably summed in all cases. For instance, when the test assembly invocation fails catastrophically due to a BadImageFormatException or StackOverflowException, the exit code included in the sum is *not* one explicitly returned by the AssemblyRunner, but instead and operating system-supplied well-known large negative number.
