Very cool! How is this "turned on"? Compile-time/boot-time option? Or just a matter of having processes running in the system that have requested timeslice/latency guarantees?

Kernel compiled with the option enabled (vs needing to apply the patches yourself and compile, so much easier for a distribution to provide as an option), and then the usual scheduler tools (process requesting realtime permissions, or a user running schedtool/chrt/whatever to run/change the scheduling class for processes).
