This patch is for default branch. It applied to 3.3 too.

> The next logical step is to make all test classes in test_xml_etree accept the ET module in some way and store it, using it to get classes & function. I.e. no more global "ET" and "pyET" at all. Would you like to add this to your patch?

I was going to do this on the next step, but if you prefer I can prepare a single patch. But it seems to me that more simple patches are easier to review.
