    Description

      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
