Yes. The scary part is the ExchangeID before the BindConnectiontoSession.
(Normally that is only done at the beginning of a new mount to get a ClientID,
 followed immediately by a CreateSession. I don't know why it would do this?)

The attached patch might get BindConnectiontoSession to work. I have no way
to test it beyond seeing it compile. Hopefully it will apply cleanly.

That's fine. I don't think that matters much.

If the attached patch works, you'll find out what it fixes.

I have no idea if getting BindConnectiontoSession working will fix this or not?
