      Observed behavior: _id values larger than the max key size are not indexed and so duplicates are not prevented
      Expected behavior: _id value larger than max key size is not allowed

      Test

      > c.drop()
true
> var big = new Array( 10000 ).toString()
> c.save( { _id:big } )
> c.save( { _id:big } )
> c.count()
2
> c.find( { _id:big, dummy:null } ).hint( { $natural:1 } ).itcount()
2
