      Description

      New stress test failure. It's reproducible, I've seen it once (in 600+ runs), on pixiebob.

      [1451952138:804734][19893:0x7f4497fff700], t, file:wt.wt, WT_CURSOR.prev: WT_CURSOR.prev out-of-order returns: returned key 0000056500.13/opqrstuvwxyzabcde then key 0000100000.00/opqrst: Invalid argument
      [1451952138:804733][19893:0x7f44a6b7e700], t, file:wt.wt, WT_CURSOR.prev: WT_CURSOR.prev out-of-order returns: returned key 0000056500.13/opqrstuvwxyzabcde then key 0000100000.00/opqrst: Invalid argument
      t: cursor.reset: WT_PANIC: WiredTiger library panic[1451952138:804790][19893:0x7f4497fff700], t, file:wt.wt, WT_CURSOR.prev: the process must exit and restart: WT_PANIC: WiredTiger library panic
