Stop: improve synchronising of reshape with whole stripes.

It is possible for 'sync_completed' to be further ahead than
we deduced from 'reshape_position'.  However we cannot read it while
the array is frozen, so it is hard to know.

Once that array is unfrozen, check and if sync_completed is ahead of
'sync_max',  push 'sync_max' well ahead if 'sync_completed' so it
will all synchronise up properly.
