This is a pyside-ism? The parent QObject takes an additional Python 
reference to the child? (I'm pretty sure this doesn't happen in C++...)

Though you bring up another point; parented QObjects (at least in C++) 
are destroyed when their parents are destroyed, which I would assume 
bypasses Python's refcounting? (Maybe the Python object would still 
exist, but would be invalid.) So that's something else to keep in mind, 
but probably rarely relevant (it's unusual that the parent would be 
destroyed while you still care about the child).
