title: when do getTempDirectory files get deleted?
body: <p>In coldfusion, when do files that are uploaded using the getTempDirectory() function get deleted?
  I'm storing a temporary file that will eventually go in a database, but I need to run some code before I push it to my database. Once it's on the database I'll want to delete it from the temp directory. How long does it stay in the temp directory?</p>
