These files are part of the SQLite transaction/journal handling. I know that they can get created and removed dynamically while making changes to the database. I think they always disappear on a tidy closedown, but can get left behind after a crash (and are presumably used for recovery on the next run).
I suspect that the handling of those files is internal to the SQLite library code and never visible to the higher level Calibre code.
