      1. Open Mongo shell.
      2. Type: NumberLong(9223372036854775807).
      3. If you got answer: NumberLong(9223372036854775807) close shell and go to step 1.
      4. More frequently you'll get answer: NumberLong("-9223372036854775808"). I think this is wrong.
      My example:
      MongoDB shell version: 2.2.2
      connecting to: dataproviders
      > NumberLong(9223372036854775807)
      NumberLong("-9223372036854775808")

      Assume that max value of 64-bit integer id 2^63-1 = 9223372036854775807
      But sometimes in mongo shell we got wrong results from NumberLong(9223372036854775807):

      MongoDB shell version: 2.2.2
connecting to: dataproviders
> NumberLong(9223372036854775807)
NumberLong("-9223372036854775808")
