+/* Some remarks on thread safety ...
+ *
+ * The thread safety of this class depends largely upon the thread safety of
+ * the underlying GSSAPI and Kerberos libraries. This code just loads the 
+ * system GSSAPI library, and whilst it avoids loading known bad libraries, 
+ * 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.
