From test_hotshot.py:

    def test_logreader_eof_error(self):
        self.assertRaises((IOError, EOFError), _hotshot.logreader, ".")
        gc.collect()

If I run python command-line interpreter, it doesn't raise exception:

>>> import _hotshot
>>> _hotshot.logreader(".")
<_hotshot.LogReaderType object at 0x3f260>
>>> 

On intel/linux, this test passes.
