I haven't still found any starvation cases, but forking time when the
system is under heavy load has increased considerable with respect to
vanilla or Con's O18.1int:
1. On a Konsole session, run "while true; do a=2; done"
2. Now, try forming a new Konsole session and you'll see it takes
approximately twice the time it takes when the system is under no load.
Also, renicing X to -20 helps X interactivity, while with Con's patches,
renicing X to -20 makes it feel worse.
