      Description

      In trying to see how reproducible the segfault in WT-896 is, I ran its CONFIG on the AWS HD box. On iteration 3 I hit this instead:

      [1394036080:615017][18815:00b7ffa5307f0000], t, file:wt.wt, session.checkpoint: ../src/btree/rec_write.c, 2345: state == WT_CHILD_MODIFIED
      

      The stack:
