History of SemaphorePackage

^;semaphore:<programming, operating system> The classic method for restricting access to shared resources (e.g. storage) in a multi-processing environment. They were invented by Dijkstra and first used in T.H.E operating system.^

On busy sites that edit a lot of textual content such as wiki pages, it can be useful to display a warning message if something is already being edited. This package does exactly that...

Please note that ((SemaphorePackage)) is quite simple and tries to keep things fast and easy to configure.
