This lets them nicely have independent error handling; an example case where that is desirable is that the old code failed to archive the logs if one of the daemons exited with an error. This also means a config file might specify just some of the smaller tasks, e.g. for a test that explicitly wants to create operational error situations. The diff looks big because of an indentation change, use "git diff -b" for a smaller diff.
