Lovely article ;-)
It's good to see this getting some attention, as RSDL seems to be a good piece of work. Starvation has been a problem in the kernel, giving short stalls now and then. A completely fair yet interactive scheduler like this one would do away with that, at the expense of ppl having to use nice probably a bit more on heavy processes like compiling.
Maybe apps like dpkg or emerge should start nicing themselves by default...
Still, RSDL gives a perfectly responsive desktop even when a make -j4 is running aside with aMule, mail etcetera, so its doing better than mainline on my system already.
And a better throughput is really an unexpected but nice benefit. Maybe worth mentioning RSDL does a bit better than mainline on the MySQL scaling issue:
