This makes the feature basically useless for anything requiring performance, since it always has to search the entire hierarchy for a late-assigned value further up. Additional work using our weak subclass hierarchy might be able to make reads slightly cheaper (giving up at first successfuly read) by walking down the hierarchy on every write and killing other vars, but the concurrency aspects of that make my head spin. Fixes jruby#1554.

... seems to fail (regress) some MRI tests? or maybe it just needs a rebase |

I applied this locally and those MRI tests are fine. Probably related to my symbol love work. |
