      Description

      I'm seeing an out-of-order return error, repeatably on pixiebob:

      t, file:wt, WT_CURSOR.prev: WT_CURSOR.prev out-of-order returns: returned key 82575 then key 82575: Invalid argument
      

      It's similar in a couple of ways to Sue LoVerso's report in WT-2575, it's a heavily-threaded, in-memory, variable-length column-store run. Here's the CONFIG:
