We use it to +synchronize between multiple processes and it was used to analyze +some differences between ACE 5.6 and 5.6.2. + +To run do: +1. Start a init-app. It will create the semaphore a go to sleep. +2. Start a worker-app while the init-app still sleeps. This worker app will +block on the semaphore. +3. The init-app wakes up and releases the semahpre and exists. +4. The worker-app will now lock the semphore and go to sleep. +5. Start another worker-app while the first worker-app still sleeps. It will +block on the semaphore. +6. The first worker-app finally wakes up and releases the semaphore and +start doing its work. + |
