I think the paper is slightly too opinionated but remember it was 1995. No stm in haskell yet. No .net or javar threading libraries. (Ok... first version of java just released.) I wonder what nice abstractions existed then? Perhaps the papers view was balanced for its time. Also maybe context switching was super expensive on a 286 or whatever was available then. Windows and I believe Linux use message loops for UI and do fine. You can use callbacks for up bound stuff. Probably ok for a lot of applications.
