Unless I'm reading it wrong, when _setevents() is called, the internal
hooks are rewired to populate the events list, rather than call the
corresponding TreeBuilder methods. So, yes, there's a TreeBuilder
somewhere, but it stands unused.
(the _setevents() method already existed on the C impl, by the way.
I added it to the Python impl to make things more regular and avoid
two separate iterparse() implementations)

What difference would that make? In the end, you mustn't mix
event-driven/non-blocking and cumulative/blocking styles of
programming, so having two separate APIs doesn't strike me as
a problem (it may be a good thing actually, for clarity reasons).
