Sorry for the glibness I am just really bored with these complaints, it really feels like the same old bikeshedding. As far as I know there is no way to make a transactional state machine without having the concept of a single, reordable work unit. Daemontools did not solve this or present a different model that was more workable. For every developer that rewrote their daemon to get rid of forking, we got more new developers with outdated learning material coming over who expected services to work like they did on some other crazy environment like Microsoft Windows.
I don't particularly care about who was a "winner" or a "loser" either. In general you cannot get away from TOCTOU on Unix without taking extreme care and avoiding things that would seem reasonable, like storing filenames in other files or using the "kill" command. In practical use I have seen no inits that make any concerned effort to solve these issues at all. That is a situation in which we all lose.
