CHANGES: - Set the internal pipe used to interrupt a domain to a non-blocking mode and remove the usage of an atomic which protect how we fill the pipe (@haesbaert, @dinosaure, robur-coop/miou#28) - Expose option to reuse addr/port when we `Miou_unix.bind_and_listen` (@ada2k, @dinosaure, robur-coop/miou#27) - Protect an illegal access to the orphan from a possibly parallel task which does not own the orphan value (@poytypic, @dinosaure, robur-coop/miou#31, robur-coop/miou#32) - Be able to pin a specific domain when we want to launch a parallel task (@dinosaure, robur-coop/miou#34) - Expose the `Miou.Backoff` module which can be useful for users (@dinosaure, robur-coop/miou#35) - Fix or improve (from the maintainance point-of-view) the `Miou.Queue` module and some internal parts of Miou about the usage of atomics (@dinosaure, @polytypic, robur-coop/miou#36, robur-coop/miou#33) - Prefer to require a `finaliser` function for the `events` value and actually close the internal `Unix.pipe` used to interrupt domain than to use `Gc.finaliser` and possibly leak file-descriptors (spotted by @hannesm, @dinosaure, robur-coop/miou#37)

It's a file-descriptor leak spotted when we do a lot of
Miou_unix.run(which is not the usual usage). However, it seems that theGc.finalisedoes not work properly (or it never triggered). It seems that we must use theclean at the shutdownoption (eg.OCAMLRUNPARAM=c) to be sure that everything (including finalisers) is cleaned but we should not impose to the user to use every-time this option.
