What about adding a pair of callbacks to the JACK API that could be registered with the suspend/resume system? When the system invokes the suspend callback Jack would mute audio output then go into soft mode, ignoring all xruns and client timeouts until further notice, then drop RT scheduling. The resume callback re-enables RT, and a few cycles later resumes the normal timing checks and unmutes audio when no xruns or client timeouts have been detected for a few consecutive cycles. The only changes would be to jackd itself AFAICT.
