+/*
+ * Original version submitted as part of PR1212
+ *
+ * This example shows a possible blocking of timeslicing if task mode is
+ * changed to timeslicing in the middle of its executing.
+ *
+ * The expected output is:
+ *
+ * Task #0's turn. Now setting turn to 1
+ * Task #1's turn. Now setting turn to 0
+ * Task #0's turn. Now setting turn to 1
+ * Task #1's turn. Now setting turn to 0
+ * Task #0's turn. Now setting turn to 1
+ * Task #1's turn. Now setting turn to 0
+ * Task #0's turn. Now setting turn to 1
+ * ...
+ *
+ * The actural output is:
+ *
+ * Task #0's turn. Now setting turn to 1
+ *
+ * Task #1 can not be dispatched also both tasks have timeslice enabled.
+ *
+ * Setting TASK_A/B_INITMODE to RTEMS_DEFAULT_MODES | RTEMS_TIMESLICE
+ * will produce the expected output.
+ *
+ * $Id$
