> Good one found by our [~mdrob]. Problem in the parent issue where failed
> attempt doubling default block size but halving the size at which roll -- so
> we end up in roughly same place only we make less small WALs in those cases
> where we are writing furiously and fail to roll before starting a new block.
> From Drob: ".../we drop default log roll to 0.5, but we don't actually
> increase the block size... AbstractProtobufLogWriter.java:164 still uses
> default HDFS block sizing and AbstractFSWAL.java:408 block size is only used
> in a log message, never actually makes it to files...".
