Since it used /tmp-dir, it continues to fail on the same server until the /tmp-dir is cleaned. (Another problem was that it uses DATA/INDEX DIR without checking for symlink, which is needed) Solution: Moved all DATA/INDEX DIR test to a new partition_basic_symlink.inc file and use this for myisam and innodb, also requiring symlinks and not_windows. (i.e. removed DATA/INDEX DIR use from several tests)
