Not to me.
You need root privileges to use RT queues.
Most interactive programs are not run as root.

"it looks good" was not my only requirement.
It should also not add code bloat, make the code less readable or
make the common case slower.

Of course, implicitly I also want that the code does something good at
all, which has not been sufficiently established so far.

I do.

His numbers did not look like it was just one application.
I got the impression that he made the common case faster.
And that is definitely something I want. ;)
