For future reference, this is less stylistically acceptable C: you've
reduced the if clause to a single statement, so the braces need
removing.
However, I don't think we should be ignoring the fact that the eh thread
failed to spawn, so I think some type of printed warning (giving the
error code) would be a much more appropriate replacement.
