[PD] pd watchdog/ non-root realtime priority?

Maybe someone can open up one of the deep PD-Linux mysteries for me...
What is PD watchdog, and how can I get him to stop barking?
I understand that, when running PD in realtime/root mode, you have
higher priority in the system, and that this priority is enough to slow
or even stop other processes when PD uses too much resource. I imagine
"pd watchdog" is a systems monitor who barks when PD uses too much CPU.
However, running rt/root, it seems he *always* barks at me, even when
using only 50% CPU. The barking isn't so bad, but the sluggish response
time of the computer and espc the GUI is!
In short, root/realtime mode is just too piggish sometimes.
I know that with Jack, there is a way to do non-root realtime priority
by making a "capabilities" patch to the kernel. Does something similar
exist for PD? And if so, would non-root realtime priority be "safer",
and thus shut the dogs up, and keep a responsive computer?
