I confirmed this is still happening by tracing with wireshark last night; so my expectation for preauthenticate was wrong as it doesn't stop the initial grab for authentication flavor; setting the header yourself does the trick for that first call.

Yes. What's interesting about this is that my authentication function works for getting and posting updates on my personal timeline.

Almost. request.PreAuthenticate still sends a double request the first time.
