I've always liked the shared libraries that print version information when executed - it's a simple ergonomic convenience. One of the central libraries in our system as, IIRC, its own main loop that's never run in normal operation - usually the process of injecting it into a target process also ensures it gets set to an entry point that'll actually do stuff. But you can execute it and it'll just sit there spinning happily on its own like some kind of weird debugging singularity. There must be something we can use it for but I'm not sure what...
