> In {{CommitLog::recover}} the list of segments to recover from is determined
> by removing the files managed by the {{CommitLogSegmentManager}} from the
> list of files present in the commit log directory. Unfortunatly, due to the
> way the creation of segments is done there is a time window where a segment
> file has been created but has not been added yet to the list of segments
> managed by the {{CommitLogSegmentManager}}. If the filtering ocurs during
> that time window the Commit log might try to recover from that new segment
> and crash.
