> Upon cancellation, the task thread is periodically interrupted.
> This helps to pull the thread out of blocking operations in the user code.
> Once the thread leaves the user code, the repeated interrupts may interfere with the shutdown cleanup logic, causing confusing exceptions.
> We should stop sending the periodic interrupts once the thread leaves the user code.
