+ * This class is used to prevent multiple calling of g_thread_init ()
+ * for GLib < 2.20.
+ *
+ * Since version 2.24 of GLib, calling g_thread_init () multiple times is
+ * allowed, but it will crash for older versions. There are two ways to 
+ * find out if g_thread_init () has been called:
+ * g_thread_get_initialized (), but it was introduced in 2.20
+ * g_thread_supported (), but it is a macro and cannot be loaded with dlsym.
+ *
+ * usage:
+ * <pre>
+ * lock();
+ * try {
+ *    if (!getInitStateAndInitialize()) {
+ *        //call to g_thread_init();
+ *    }
+ * } finally {
+ *    unlock();
+ * }
