True, but that doesn't explain why the first sourced invocation succeeds, but all invocations thereafter fail. Is there a reason for this behavior? Why should a call to trap succeed or fail depending on whether the trap is already set or not? If that's expected behavior, I would certainly like to document it! Thanks, - Scott
