-----------------------------------------------------------------
the files in new base_x may not even be readable so likely this needs base_x_x
so that the whole dir is skipped on read
Another issue to think about: if 'x' aborts when does the metadata for it get
cleaned? There is nothing in (COMPLETED_)TXN_COMPONENTS about it.
Add logic to write to txn_components and special handling for base_x when x is
aborted to skip it? Normal compaction will never produce base_x with x opened
since it never includes any open txns.
