The CThreads package provides mutex lock and unlock
operations, condition signal and condition broadcast.
Documentation on CThreads is available from CMU
as part of our Mach releases.   I'm, not really
certain why this was not mentioned in the article
you read unless something else was being discussed
other than cross-thread synchronization.
