+ * If you do not call the StreamGobbler's <code>read()</code> method often enough
+ * and the peer is constantly sending huge amounts of data, then you will sooner or later
+ * encounter a low memory situation due to the aggregated data (well, it also depends on the Java heap size).
+ * Joe Average will like this class anyway - a paranoid programmer would never use such an approach.
+ * <p>
+ * The term "StreamGobbler" was taken from an article called "When Runtime.exec() won't",

+	 * If a thread uses a particular shared variable only after locking a
+	 * particular lock and before the corresponding unlocking of that same lock,

+	 * memory after the lock operation, if necessary, and will copy back to main
+	 * memory the value most recently assigned to that variable before the
+	 * unlock operation.
