* Makefile.am, configure.ac: Add test case for the
	_Thread_queue_Enqueue_priority interrupt critical section where the
	TCB we are using as a current pointer is removed from the thread
	queue when we flash interrupts while searching forward.
	* spintrcritical06/.cvsignore, spintrcritical06/Makefile.am,
	spintrcritical06/init.c, spintrcritical06/spintrcritical06.doc,
	spintrcritical06/spintrcritical06.scn: New files.

+directives:

+  _Thread_queue_Enqueue_priority
+    - interrupt synchronization
+  rtems_task_restart
+  _Thread_queue_Extract_priority
+
+concepts:
+
++ Ensure that removing the "search task" from the thread queue while we
+  are looping and enqueuing another works as expected.  This case is where
+  the TCB we are using as a current pointer is removed from the thread queue
+  when we flash interrupts WHILE SEARCHING FORWARD.
+
+NOTE: There is no way to know this case is hit from a test perspective.  The
+      test just runs and we check the coverage report.
