Subprocess and threads
======================
asyncio supports running subprocesses from different threads, but there
are limits:
* An event loop must run in the main thread
* The child watcher must be instantiated in the main thread, before executing
subprocesses from other threads. Call the :func:`get_child_watcher`
function in the main thread to instantiate the child watcher.
