Hi there.
I have a suspend function in which a resource is opened and later closed in a finally block. Upon cancellation I would expect to receive a CancellationException. But I don't receive any und the finally block is not executed. Does anyone know why?

Where are you catching the exception? Subsequent suspend functions don’t run upon cancellation. Your best bet may be to add a cancellation exception handler on launch

I catch it inside the function. And because this function is part of a library, I don't have control over how it is launched 

```
suspend fun doStuff() {
    try {
        val resource = openResource()
        callOtherSupendFunction(resource)
    } catch (e : CancellationException) {
        // never reached here
    } finally {
        resource.close() // not executed when cancelled
    }
}
```

I found the issue. Inside `callOtherSupendFunction()` was a `suspendCoroutine{ }` block, which I had to replace with `suspendCancellableCoroutine{ }` block to receive the CancellableException.
