  * Topic: Threads
  * libmosquitto provides thread safe operation, with the exception of
  * <mosquitto_lib_init> which is not thread safe.
+ *
+ * If your application uses threads you must use <mosquitto_threaded_set> to
+ * tell the library this is the case, otherwise it makes some optimisations
+ * for the single threaded case that may result in unexpected behaviour for
+ * the multi threaded case.
