[MITgcm-support] SSH drift and obcs again

[Thomas Haine]

Hi Martin, 

I'm confused. exp4 has zero eta drift in the standard configuration in
the latest code. The cg2d rhs is also very near zero. Yet there is
normal flow through the domain. If I add a meridional component to the
normal flow the results are, essentially, the same. 

Also, (max, min) eta is +/-10m after 1 step. Is this correct?

So, I can't reproduce the problem I've seen in exp4 and I don't know
why.

Tom.
