--------------------------------------------
I tested bootstrap on 0.5 and this did not occur, for what it's worth.

> I started a 3 node cluster with RF=3 and loaded about 3M keys into it. I proceeded to bootstrap a 4th node and it completed. Upon performing a read test, I found that two nodes could find all keys, and two nodes could find none, depending upon which machine I queried. Here is the ring output:

> Token 0 was the newly bootstrapped node. Tokens 127605887595351923798765477786913079296 and 85070591730234615865843651857942052864 were able to read all keys, the other two nodes were not.
