the reason it seems is that with some particular timing, the stacks.get() returns a stack without the 'outputs' attribute:

    Fix functional test_signal_during_suspend

    With some particular timing the stack returned by stack.get() is still
    in SUSPEND_IN_PROGRESS and lacks `outputs` attribute.

    Wait not only for nested stack to go to SUSPEND_COMPLETE, but for parent
    stack too.
