Can we implement eventfd(2) as documented here <https://man7.org/linux/man-pages/man2/eventfd.2.html>? It would only be available on the Linux platform, and one of the benefits would be the ability to create synchronisation primitives on said platform that can block on normal threads, and be awaited on in coroutines (without busy looping inside said coroutine). Currently the best place I can think of to put it would be in one of the Networking and Interprocess Communication modules (possibly `select` or `socket`?). The fact that it's Linux only shouldn't be an issue, since much of the contents of `select` is OS dependent.
