+ * </p>
+ * <p>
+ * STDERR output can be supplied as well, but due to compatibility with
+ * older Android versions, wantSTDERR is not implemented using
+ * redirectErrorStream, but rather appended to the output. STDOUT and STDERR
+ * are thus not guaranteed to be in the correct order in the output.
+ * </p>
+ * <p>
+ * Note as well that the close() and waitForIdle() methods will
+ * intentionally crash when run in debug mode from the main thread of the
+ * application. Any blocking call should be run from a background thread.
+ * </p>
+ * <p>
+ * When in debug mode, the code will also excessively log the commands
+ * passed to and the output returned from the shell.
+ * </p>
+ * <p>
+ * Though this function uses background threads to gobble STDOUT and STDERR
+ * so a deadlock does not occur if the shell produces massive output, the
+ * output is still stored in a List<String>, and as such doing
+ * something like <em>'ls -lR /'</em> will probably have you run out of
+ * memory when using a {@link Shell.OnCommandResultListener}. A work-around
+ * is to not supply this callback, but using (only)
+ * {@link Shell.Builder#setOnSTDOUTLineListener(OnLineListener)}. This way,
+ * an internal buffer will not be created and wasting your memory.
+ * </p>
+ * <h3>Callbacks, threads and handlers</h3>
+ * <p>
+ * On which thread the callbacks execute is dependent on your
+ * initialization. You can supply a custom Handler using
+ * {@link Shell.Builder#setHandler(Handler)} if needed. If you do not supply
+ * a custom Handler - unless you set
+ * {@link Shell.Builder#setAutoHandler(boolean)} to false - a Handler will
+ * be auto-created if the thread used for instantiation of the object has a
+ * Looper.
+ * </p>
+ * <p>
+ * If no Handler was supplied and it was also not auto-created, all
+ * callbacks will be called from either the STDOUT or STDERR gobbler
+ * threads. These are important threads that should be blocked as little as
+ * possible, as blocking them may in rare cases pause the native process or
+ * even create a deadlock.
+ * </p>
+ * <p>
+ * The main thread must certainly have a Looper, thus if you call
+ * {@link Shell.Builder#open()} from the main thread, a handler will (by
+ * default) be auto-created, and all the callbacks will be called on the
+ * main thread. While this is often convenient and easy to code with, you
+ * should be aware that if your callbacks are 'expensive' to execute, this
+ * may negatively impact UI performance.
+ * </p>
+ * <p>
+ * Background threads usually do <em>not</em> have a Looper, so calling
+ * {@link Shell.Builder#open()} from such a background thread will (by
+ * default) result in all the callbacks being executed in one of the gobbler
+ * threads. You will have to make sure the code you execute in these
+ * callbacks is thread-safe.
