In Fedora 12 with Planet CCRMA Jack Audio Connection Kit, does starting jack with qjackctl suspend pulseaudio?

If not, how can I add pulseaudio suspend (and resume) to qjackctl?

How can I tell if pulseaudio is running, is there a terminal command for pulseaudio status?

I have searched through the jackaudio.org, pulseaudio.org, qjackctl.sourceforge.net and other sites, and didn't find an obvious answer.
http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workarounds has some info but not about jack.

Thanks,
