@ -1011,8 +1011,13 @@ reftable stack, reload `tables.list`, and delete any tables no longer mentioned
in `tables.list`.
Irregular program exit may still leave about unused files. In this case, a
cleanup operation can read `tables.list`, note its modification timestamp, and
delete any unreferenced `*.ref` files that are older.
cleanup operation should proceed as follows:
* take a lock `tables.list.lock` to prevent concurrent modifications
* refresh the reftable stack, by reading `tables.list`
* for each `*.ref` file, remove it if
** it is not mentioned in `tables.list`, and
** its max update_index is not beyond the max update_index of the stack
