DROP DATABASE would internally execute DROP TABLE on every contained table and finally remove the directory. In InnoDB, DROP TABLE is sometimes executed in the background. The table would be renamed to a name that starts with #sql. The existence of these files would prevent DROP DATABASE from succeeding. CREATE OR REPLACE DATABASE can internally execute DROP DATABASE if the directory already exists. This could fail due to the InnoDB background DROP TABLE, possibly due to some tables that were leftovers from earlier tests.
