I have never claimed that they are unfixable. However, reducing latencies
does not remove a disturbance.

Or, to come up with a car analogy: it's a bit as if at a repair shop
you complained that your car has a scratch on its cooler grid that
annoys you, and you insisted that it be outfitted with a new diesel
engine which needs no cooler grid (throwing away the nice Hemi block
it has currently) - and ignored the mechanic's opinion that he loves
the Hemi and that to him the scratch looks very much like bird-sh*t
and that a proper car wash might do the trick too ;-)

Nope. Its like you want to get rid of your car and the person you talk to
tries to convince you to keep it. He claims if you would just wash it and
repair it then it will be maybe become almost invisible and you would have
reached your goal of not having a car.

That would benefit ordinary Linux users too, not just rare isolation
apps.

We are talking about apps that need isolation here not regular app.
