+ * it cannot determine the thread safety of the the code it loads.
+ *
+ * When used with a non-threadsafe library, it is not safe to simultaneously
+ * use multiple instantiations of this class.
+ *
+ * When used with a threadsafe Kerberos library, multiple instantiations of
+ * this class may happily co-exist. Methods may be sequentially called from
+ * multiple threads. The nature of the GSSAPI protocol is such that a correct
+ * implementation will never call methods in parallel, as the results of the
+ * last call are required as input to the next.
