Another thing is that such temporary indexes may be created on the user's local drive instead of application directory on the network. That simplifies the uniqueness problem - SYS(2015) is enough - and kind of speeds up the indexing. Also, the application on quitting may just wipe out all temporary indexes on local temp directory at once.
