    Maybe. There are lots of other error numbers that are equally useful
    for testing. If you really want a way to inject known errors into
    I/O system calls, why not go the whole hog and implement a virtual
    filesystem that returns the required error:
    .../EPERM just returns EPERM
    .../ENOENT just returns EPERM
    etc

    Of course, you've then got to decide which of open(), close(), read()
    write(), ioctl(), fcntl() etc should succeed and which should return
    an error. This rapidly becomes unworkable.

    Overall, IMHO, the benefits are minimal and don't warrant the effort
    of implementing and maintaining the code.
