I'll wait for this then.

Once it works it may be worth to try an experiment with the last 
remaining wait state and see whether also that one can be removed. I am 
not sure whether we should have it since it only negatively affects 
performance and it is also part of the device's state, so it would not 
be so easy to remove once we have it.
