I think the point is that restarting is not 100 % compatible due to T
coupling. We would therefore have to hack the code such that restarting
will be 100 % identical even with T and P coupling.  We will have to
store additional information about velocities at previous time steps.
Since we are planning to make some kind of "checkpoint" file, we should
take care that it is correct then. I can't promise anything right now
though...
