    VSTH is testing wordexp() to ensure that it is not a cancellation point.
    According to XPG5 XSH, wordexp() is not in the list of
    "must have" cancellation points or the list of "may have" cancellation
    points and this test backs that up. Our implementation fails the test.




    We believe that wordexp() should have been included in the table of
    "may cancel" functions. Since it must be able to function exactly as shell
    command line word expansion does, that means that it must be able to open a
    directory, read it, and the close it. All three operations are themselves
    cancellation points (open, read, close) which may potential block
    indefinitely.
