Over the years a lot of issues have accumulated forasyncio.wait_for and the code has become complicated. Theasyncio.timeout can be used to simplify this a lot and will also fix bugs which are already fixed or don't exist inasyncio.timeout. This rewrite won't be backported.asyncio.wait_for should be nothing more than a wrapper aroundasyncio.timeout.
