Semaphores are a good idea for different scenarios. My main application is a server performing downloads and compilations on demand. The reader is just a GUI added afterwards for people who prefer coloured pictures and 2-buttons over 100 keys. Both scripts are completly independent of one each other. I did not want to alter the source of the files.
Nevertheless, it is good to have red coloured error messages.
