[pulseaudio-discuss] Rtkit and PulseAudio rlimit_rttime mismatch

Ricardo just noticed that a bug fixed in rtkit 0.11 causes a mismatch 
between PulseAudio and RtKit.

In short, PulseAudio sets its default RLIMIT_RTTIME to one second, and 
rtkit by default refuses to give realtime priority to anything above 200 ms.

So, should we change rtkit to allow an RLIMIT_RTTIME of one second, or 
modify PulseAudio to have itself killed after 200 ms of rtprio? Opinions?

(And btw, any chance we can deprecate rtkit altogether sometime, given a 
recent systemd and kernel?)
