title: Why can't I see a runaway infinite print in the top list
body: <p>I am running some code on the head node of a remote machine. Occasionally there is some issue and an infinite print out ensues. I try to <code>ctrl-c</code> but this doesn't seem to work.</p>
  <p>If I then open a new terminal and look at <code>top -u myusername</code> this infinite process which I assume is taking up lots of CPU doesn't seem to appear.</p>
  <p>My questions: (i) what is the best way to kill something like this when it happens? and (ii) why can't I see the runaway process in the <code>top</code> list.</p>
