It seems to have helped, but not solved the problem. It seems like more
of the processes are running, and not getting hung, but there were a few
that did hang. I was able to do a 'top->bottom' kill -9 with a 'sleep 1'
between, and in one case it worked, but in another, I had to go to the
node again and kill -9 the process there.
