When a builtin or extension module is imported for the first time, while a
subinterpreter is active, the module's init function is now run by the main
interpreter first before import continues in the subinterpreter.
Consequently, single-phase init modules now fail in an isolated
subinterpreter without the init function running under that interpreter,
whereas before it would run under the subinterpreter *before* failing,
potentially leaving behind global state and callbacks and otherwise leaving
the module in an inconsistent state.

Improved behavior of :class:`asyncio.TaskGroup` when an external cancellation
collides with an internal cancellation. For example, when two task groups
are nested and both experience an exception in a child task simultaneously,
it was possible that the outer task group would misbehave, because
its internal cancellation was swallowed by the inner task group.
In the case where a task group is cancelled externally and also must
raise an :exc:`ExceptionGroup`, it will now call the parent task's
:meth:`~asyncio.Task.cancel` method. This ensures that a
:exc:`asyncio.CancelledError` will be raised at the next
:keyword:`await`, so the cancellation is not lost.
An added benefit of these changes is that task groups now preserve the
cancellation count (:meth:`asyncio.Task.cancelling`).
In order to handle some corner cases, :meth:`asyncio.Task.uncancel` may now
reset the undocumented ``_must_cancel`` flag when the cancellation count
reaches zero.
