I sometimes have an rtkit-daemon process eating 100% of my CPU and making the system unresponsive. I reboot and things are fine after that. What is rtkit-daemon supposed to do and why would it be sometimes eating up 100% of my CPU?

RealtimeKit is a D-Bus system service that changes the scheduling policy of user processes/threads to SCHED_RR (i.e. realtime scheduling mode) on request. It is intended to be used as a secure mechanism to allow real-time scheduling to be used by normal user processes. Overall, I would not expect it to peg out CPU usage. What happens if you let it run its course and do not reboot? I would be curious to know how long rtkit-daemon is active at any given instance.
