> 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.
