[OT] bad records in HFS+ volume

The Extents Overflow File of one of my HFS+ partitions has a few records referencing fileIDs (aka NSFileSystemNumber or unique catalog node ID (CNID) ) which do not exist (i.e. are not in the Catalog File).

Disk Utility (and fsck) do have no problem with this and report no error.

But what will happen when the CNID wraps around and these non-existing iIDs will be used again?
Will the file system notice that dead records exist in the Extents file and remove them?
Or will a terrible confusion be the result?

Currently I create about 1 million IDs per year, so the CNID wrap-around is not really imminent.

Gerriet.
