If you redirect a file handle to an already existing one, there are far
fewer things that can go wrong. In fact, when you open a regular file
the most common errors are: file not found, permission denied, and disk
full. If you have a real hardware problem, your program might be the
first to find it but you will have programs failing all over the place.
Hardware errors are usually fairly obvious.
