+
+ * modules/clib/clib.c: bugfix: timeout for await is specified in
+ seconds, not milliseconds
+
+ new: allow timeouts to be specified with try function on mutexes
+ and semaphores
+
+ This allows mutexes and semaphores to be locked/read with an
+ absolute timeout value, using try (MUTEX,TIME) or try (SEM,TIME)
+ instead of just try MUTEX or try SEM. This works analogously to
+ await (COND,TIME) which has always been available.
+
+ NOTE: The new try timeout functionality is only available on newer
+ systems which already have the pthread_mutex_timedlock and
+ sem_timedwait routines in the POSIX threads library. Otherwise the
+ timeout value will just be ignored, i.e., the routines will return
+ immediately (as if no timeout value was specified).
