How to deal with cascading write?

I did some code to update the child partner records automatically upon modification of a field, stock_owner_id. I overwrote the "write" function to achieve that.

    def write(self, vals):
        """ This will overwrite children stock owner to the same as the current one.
        soid = vals.get('stock_owner_id')
        if soid is not None:
            children = self.search([('parent_id', 'child_of', self.ids)])
            if children:
                children.write({'stock_owner_id': soid})
        result = super(Partner, self).write(vals)
        return result
The problem is that the "write" function is triggered for each child write and that trigger other useless queries on the database.

Any suggestion to prevent that behaviour and still update all my children in bulk?
