+    """Replace weakref.WeakSet to address Python 3 bug.
+
+    Under heavy threading operations that schedule calls into
+    the asyncio event loop, Task objects are created. Due to
+    a bug in Python, GC may have an issue when switching between
+    the threads and objects with __del__ (which various components
+    in HASS have).
+
+    This monkey-patch removes the weakref.Weakset, and replaces it
+    with an object that ignores the only call utilizing it (the
+    Task.__init__ which calls _all_tasks.add(self)). It also removes
+    the __del__ which could trigger the future objects __del__ at
+    unpredictable times.
+
+    The side-effect of this manipulation of the Task is that
+    Task.all_tasks() is no longer accurate, and there will be no
+    warning emitted if a Task is GC'd while in use.
+
+    On Python 3.6, after the bug is fixed, this monkey-patch can be
+    disabled.
+
+    See https://bugs.python.org/issue26617 for details of the Python
+    bug.
