This happens, on Windows, when there is an IndexReader still reading those files. IndexWriter will periodically (after a merge completes or a new segment is flushed) retry deleting those files, but it won't succeed until no reader has a given file open anymore.
IW also deletes unreferenced files when it's first opened. So if you want to force it to try to delete, close your current IW and open a new one (with create=false).
