    Problem Text
    This test may fail on implementations that detect an invalid id before
    detecting a non-existent path.

    The test fails to produce ENOENT because it uses an id field of zero.

    According to the SPEC 1170 documentation on ftok():

    Only the low-order 8-bits of id are significant. The behavior
    of ftok() is unspecified if these bits are zero

    Thus I conclude it is wrong to use the following as the basis for
    testing ftok(): key = ftok("", 0);

    Our implementation returns EINVAL for the above test and since the
    behavior is unspecified when id is 0, our behavior is acceptable.

    If the 0 in the ftok call is changed to 1 the tests pass.
