* Create a temporary directory. This directory is NOT deleted when the JVM stops, because using File#deleteOnExit()

* <ol>
* <li>deleteOnExit() only deletes for normal JVM shutdowns, not crashes or killing the JVM process</li>
* <li>deleteOnExit() only deletes on JVM shutdown - not good for long running server processes because 3 :</li>
* <li>The most evil of all - deleteOnExit() consumes memory for each temp file entry. If your process is running for months,
* or creates a lot of temp files in a short time, you consume memory and never release it until the JVM
* shuts down.</li>
