Major - P3 This renders covered indexes ineffective when shardingState.needShardChunkManager(pq.ns()) is true. Not sure if this is true in all sharding setups or just some.
DiskLoc cl = _c->currLoc();
if ( _chunkManager && ! _chunkManager->belongsToMe( cl.obj() ) ) { // TODO: should make this covered at some point
_nChunkSkips++;
// log() << "TEMP skipping un-owned chunk: " << _c->current() << endl;
