It's really inefficient to (ab)use the TDB key store as a bitmap to find out if we've already written a block to the undo file, because the tdb code is reads the database key btree disk blocks for *every* query. Changing that logic to a bitmap reduces overhead by a large margin -- the overhead of using undo_io while converting a 2TB FS to metadata_csum is reduced from 55 minutes to 45.
