The asyncio.create_subprocess_exec function is essential for using subprocesses in coroutines, so add support to do this for python2. This paves the way for extensive use of coroutines in portage, since coroutines are well-suited for many portage tasks that involve subprocesses. I'll be posting a patch soon.
