> this test can throw OOMs, because it uses a FileReader and readLine to read
> the commit log. However, some commit logs are fully allocated, but not
> initialized, (all 0s) so finding an EOL means reading 134M of data. Even for
> commit logs that have data they really aren't filereader-type streams.
> changed to do simple byte finding in the streams instead.
