Thanks! I'll check it out today. Actually test_support uses unittest and
doctest to execute the module's tests. Once doctest support is included in
py.test I won't have to use test_support anymore for the doctests. Further
down the line, once unittest support is included, well you can see where I
am going. The test_support will no longer be needed...

I have a patch for this that I am currently working on. I have to write a
couple more tests to cover all the various ways you can import things into
a namespace.
