I finally got around to investigating this further.  If I enable the
"build packages with debugging symbols' the problem goes away :(

If I interrupt the processes with gdb and step, I see that it's
looping through the same function over and over, for some reason.  I
did try procps-3.2.8, to no avail.

Any ideas?
Thanks,
