2nd try at not adding (so not messing with locks of) unparsed stuff to Exec env apparently isRawData has to hang off DKV.get()
2nd try at not adding (so not messing with locks of) unparsed stuff to Exec env
apparently isRawData has to hang off DKV.get()

      if( val.isFrame() ) {
        val = DKV.get(k);       // Fetch the whole thing
        if( val == null ) continue; // Racing delete got it?
->      if( val.isRawData() ) continue; // don't add unparsed stuff

this passes build.sh junit/R tests plus my test
