I think you should probably do it in extras_finish_step() instead, and
it is s% dt_next. This is what we have done to control the timestep for
accreting WD setups.
I think s%dt is the either the timestep currently being attempted (when
extras_check_model() is called) or the timestep just finished (when
extras_finish_step() is called).
There is also a string somewhere that indicates what is constraining the
timestep and is printed in the summary info to the terminal, but I don't
know what that is called. That should probably be changed too, to
something like "mylimit" or something more meaningful.
