npub1srcgh979ychudzrha7asxa7kvennpghghzzadmv5gcunfw5p72qs6xfms4 (npub1src…fms4) Triggers memories about the green threads Java had in the first releases (maybe even went into 1.0, don't remember). IIRC those have been awful. Maybe because they only ran on one OS thread and couldn't catch all blocking I/O? Don't quite remember.
Though in a way I never quite understood why this is better. The OS is doing exactly the same thing already for OS threads. An OS thread that is blocked on I/O doesn't consume CPU either.
