It could be refactored to support a different subset of event types -- maybe just sockets, no latches and obviously no 'postmaster death'. But figuring out how to make latches work between threads might also be interesting for future projects... Maybe Fabien has completion-based I/O in mind (not just "readiness"). That's something that some of those libraries can do, IIUC. For example, when your thread wakes up, it tells you "your socket read is finished, the data is already in your target buffer". As opposed to "you can now call recv() without blocking", so you avoid another trip into the kernel. But that's also something we'll eventually want to figure out in the server.
