That would work for examples, but not tests. Many packages have scripts that are in the tests directory, not just test code in the .Rd files. What I think you should use is my suggested HowMuchTimeLeftBeforeTimeout() function, but if that's not writeable, then simply having a TIMELIMIT environment variable or similar, so your code could see if the there's a timeout pending.
