/// real ScrSection object.
/// We come here a lot (gets called from Update handler), so we don't want to construct
/// a ScrSection object here but get the value we're interested in directly from the
/// cache. Creating a ScrSection object checks if the HVO is valid. In doing so it does
/// a query on the database (select Class$ from CmObject...) This happens only in Debug,
/// but getting the interesting value directly from the cache makes it easier to do SQL
/// profiling.
