OK done.  It's checked in the release1 branch.

I have never used the joinpickup so I can't help you there.

There is nothing wrong with seaice_pickup.F.  It works both with multi-file or
with single-file I/O in the ecaxt same way as checkpoint.F.  It's just that
the number of sea-ice variables is different from the standard pickup files.
If you run on the same number of CPUs all the time, there is no need to join
the pick-up files, just rename to their appropriate permanent checkpoint name.
