+ *Test ClientWaitSync() returns correct values
+ *
+ *
+ *Section 5.2.1(Waiting for Sync Objects) of OpenGL 3.2 Core says:
+ *"ClientWaitSync returns one of four status values. A return value of
+ * ALREADY_SIGNALED indicates that sync was signaled at the time
+ * ClientWaitSync was called. ALREADY_SIGNALED will always be
+ * returned if sync was signaled, even if the value of timeout is
+ * zero. A return value of TIMEOUT_EXPIRED indicates that the
+ * specified timeout period expired before sync was signaled. A re-
+ * turn value of CONDITION_SATISFIED indicates that sync was signaled
+ * before the timeout expired. Finally, if an error occurs, in
+ * addition to generating a GL error as specified below,
+ * ClientWaitSync immediately returns WAIT_FAILED withoutblocking."
+ *
+ *
+ * NOTE: This test sporadically fails for some reason...
