+// For barriers, condition variables, mutexes, and read-write locks, [TSH]
+// [Option Start]  if the process-shared attribute is set to
+// PTHREAD_PROCESS_PRIVATE, [Option End]  only the synchronization object at the
+// address used to initialize it can be used for performing synchronization. The
+// effect of referring to another mapping of the same object when locking,
+// unlocking, or destroying the object is undefined. [...] The effect of
+// referring to a copy of the object when locking, unlocking, or destroying it
