+** Bug fix of priority
+There was a severe bug about the configuraion of priority setting of
+exceptions.  As we don't use any inter-lock between interrupts hander
+and timer expiration handler, these priorities should be equal.  If
+not, timer expiration handler might interrupt the execution of
+interrupts handers.
