// The script should assume that it can be interrupted at
// any point, and be able to continue by re-running the script.
// Fatal errors, however, should be allowed to throw exceptions,
// which will be caught by the framework.
// It shouldn't do anything that might take more than a few
// seconds, for systems with low timeout values.
