+ * @brief Pthread Get/Set Concurrency
+ * @ingroup POSIXAPI
+ *
+ * Per the Open Group specification, when user pthreads are mapped 1:1
+ * onto kernel threads, the implementation simply tracks an internal
+ * variable whose initial value is 0. If it is set, subsequent calls to
+ * obtain the value return that previously set.
