      I have documents like:

      {
  "_id": ObjectId("4cf567c4e4b08fffc3947252"),
  "kodoId": 1167286,
  "p": "/term/Japanese/Tanzania",
  "pl": "/term/japanese/tanzania",
  "r": "/viewWord.jsp?wordId=12083307",
  "l": "eng",
  "cd": new Date("2010-11-30T22:08:20+0100")
}

      and a hashed index on 'pl' added yesterday. Some unit tests now fail with:

      Overflow hashed AND stage buffered data usage of 33554468 bytes exceeds internal limit of 33554432 bytes

      on query

      {pl: 'blah', l: 'eng'}

      with sort

      {cd: -1}

      for some reason if I switch to sort {_id: -1} the error goes away.
