Not to mention the fact that Unix domain sockets on Linux are really,
*really* fast; performance data of that age is in general suspect; it is
several major releases old (at least). And Futexes are indeed a new
very interesting possibility.
In short, some serious investigation given the new facilities on current
releases are in order. But then again, much of the system performance
work on X is now *very* stale in general; we have better facilities
than select/poll these days as well (and a typical X server now
has many more connections open; 25 as I compose this message).
Some serious performance work is in order, and not just the
"x11perf" flavor micro optimization work either.
