OK.  When I tried the same it was unstable and it oscillated for a while
during initialization or after surface forcing shocks.  Because of
Adams-Bashforth, I guess.  Any disadvantage to using
forcing_In_AB=.FALSE. ?

If the configuration with Adams-Bashforth is not needed and if the
sea-ice model is stable that way, then maybe we can get rid of
surfaceTendencyTice alltogether.  Just have freeze_surface also return a
flux in qnet?

Oops sorry.  I thought this was an oversight
but I am not aware that it causes any problem.
Let's put it back then.
