 Hey hey everyone,
 I've looked more into this problem and found that JACK will start by using
 between one and two percent of the CPU, but will gradually require more.
 After a day JACK's CPU usage stands at about 65-85%.

 Usage: currently only mpv (multimedia player, completely shut down after
 every use). No persisting audio connections, no other realtime and CPU
 hungry applications.

 JACK Version: 0.121.3
 Kernel Version: 3.9.0-rc6 SMP PREEMPT
 CPU scheduling/scaling_governor: powersave
 CPU setting: 800MHz single-core (of a 3GHz quadcore)
 Underlying soundcard device: ALSA multi with two MAudio Delta 1010 LT
 cards, sync'ed via S/PDIF.
 JACK commandline:
 jackd --timeout 4500 -R -d alsa -C cdelta -P pdelta -r 48000 -p 256 -z
 shaped
 short-time load average: 0.47 (decreasing for longer periods).

 If more information or experimentation, to identify the issue, is
 necessary, please let me know.

 Thank you for any help and hints in the right direction.

 Ta-ta,
