Description: As discussed in [1] and [2], this PR makes asyncio.get_event_loop() to always return the currently running event loop when it is called from a coroutine. The patch adds two new functions: asyncio._set_current_loop() and asyncio._get_current_loop(). Both functions are thread-specific and are considered as low-level APIs, intended to be used by third-party loop implementations only. Even though they have a leading underscore, they will be documented as public asyncio API. loop.run_forever() is modified to call asyncio._set_current_loop() and asyncio._get_current_loop(). asyncio.get_event_loop() is modified to check if there is a current loop set by calling asyncio._get_current_loop(). If there is no current event loop, it returns the result of get_event_loop_policy().get_event_loop() (old behaviour). The biggest part of the patch is fixing unit tests: all test classes call super().setUp(). test_utils.TestCase.setUp patches asyncio._get_current_loop() to always return None. This change is to make sure that the loop is still being passed explicitly within asyncio. [1] PR: #355 [2] https://groups.google.com/d/msg/python-tulip/yF9C-rFpiKk/tk5oA3GLHAAJ
