FML::Cache::Ring holds data with size limit but without time limitation.
It is suitable for debug since the debug data is expected not to eat disk.
This class holds data in files in a directory such as $ml_home_dir/var/db/. For example, files named as db/1 .. db/100 are created. These files are used repeatedly.
RingBuffer class is integrated into FML::Cache::Ring class. FML::Cache::Ring is derived from File::CacheDir class.
