I know you didn't want this answer, but, is there a chance you can
figure out why you are getting the watchdog message in Pd in the first
hand place?

Did you already check the results of
	aptitude search watchdog

I just found these:

> s_watchdog.c is the source of pd-watchdog, which was spawned in sys_startgui(). pd-watchdog monitors its stdin for any input, timing out after 5 seconds if nothing was received. In this case it kills pd with a SIGHUP, but normally it will continue looping as long as characters are received from pd' at a rate of at least one every 5 seconds. So if pdtk_watchdog calls pd every 2 seconds and glob_watchdog() sends a CR each time through the pipe, everything runs smoothly.

Please forgive me, but why do you run Pd as root? Do you really need to
do so?
