This is 3.5+ only as 2.7 does not have the module and 3.4 does not have the 2 test_xyz_tb functions that failed. This works OK on Win7.

What system did you use? (System dependence is odd, but there it is ;-)

The obvious fix is to reduce 'expected' to the common part, and at least for the second test, split into 2 assertIns.
