After conversion in #202 of the qa_rational_resampler script to the new top_block code, it no longer passes.

The failures appear as extra or missing samples at the beginning of the output data. For example:

<pre>

======================================================================
FAIL: test_000_1_to_1 (+main+.test_rational_resampler)
----------------------------------------------------------------------
Traceback (most recent call last):
File "./qa_rational_resampler.py", line 102, in test_000_1_to_1
self.assertEqual(expected_result, result_data)
[[AssertionError]]: (-936.0, 1186.0, -112.0, 339.0, -460.0, -167.0, 582.0) != (1186.0, -112.0, 339.0, -460.0, -167.0, 582.0)
</pre>



The code has been disabled in the #202 working branch and will remain disabled after the merge into the trunk.
