However, there are closed-source and/or frozen-source apps where it's not practical to rewrite or rebuild the app. Does it make sense to break the behaviour of all of these?


See the background and answers to that in:

there's plenty of recourse possible to all possible kinds of apps. Tune the sysctl flag in one direction or another, depending on which behavior the app is expecting.

Yeah, I read those threads.

It seems like the fundamental source of the disconnect is that the tasks used to be sorted by priority (thus making it easy to bump a yielding task to the end of that priority level) while now they're organized by time (making it harder to do anything priority-based). Do I have that right?
