Message 270175 - Python tracker

In my patch, test_asyncio runs against C version Future.

I saw how test_json tests against C version and pure Python version.
But test_asyncio is more larger than test_json.

Before working on it, could someone give me idea to run whole test_asyncio
with and without C version Future easily?

And, which is master repository of asyncio? github? or hg.python.org?
If github, can I send separated pull request changing test_asyncio after
this patch is merged?
