What I need help with most right now is a suggestion of where the unittests should go. There are too many of them to all put in one file. Some options:

asyncio/test/*_test.py
asyncio/test/test_*.py
test/test_asyncio/<either of the above>

What's the best current practice?

(I also want to add some hacks so that the files can actually be identical in the stdlib and in the separate 3rd party repo, otherwise keeping the two in sync will be too much work.)
