edit: Actually there are some fairly decent systems for IPC now, with the Mach kernel from CMU probably being the most popular example. Most systems with micro-kernels probably have something similar, and of course dbus is there, and Android intents.
I think Applescript deserves a mention here, because although it's a rather weird language, the IPC stuff is really really easy.
