They should disappear when the last program holding them open closes them or terminates. So I'm guessing that you have a searcher or some such still accessing the files. This is why your searcher doesn't see new additions until you reopen it, the "snapshot" the literature talks about is just the old files.
Do note a common pitfall with Lucene's reopen is that reopen does NOT close the underlying reader, you have to do that yourself. See the docs for IndexReader.reopen, it even has a code snippet. So no, don't worry about it *if* your program is closing its IndexReaders/Writers correctly.
