      The current cache management code will instantiate the history for every page it accesses that is in WT_REF_LIMBO state - that should only be necessary if the transaction visibility rules mean the reader needs the content in the lookaside table.

      We should avoid transitioning the page to WT_REF_MEM when possible.
