> 1. The name node should create a log message when entering the "extension" period of
safe mode after achieving the minimal replication threshold.
> Logging state changes is a Good Idea. When diagnosing 2159, there is no evidence whether
the name node is in the extension period or not.
> 2. When in safe mode, the name node should periodically explain _why_ it is still in
safe mode. (2159 again)
