Entries in the hh3cSysBtmLoadTable are created and deleted using
the hh3cSysBtmRowStatus object.
When a new row is being created and the number of entries is
hh3cSysBtmLoadMaxNumber, the row with minimal value of
hh3cSysBtmLoadTime and the value of hh3cSysBtmFileType is none(2),
should be destroyed automatically.
