  > How is the pause and resume done? Perhaps by sending SIGSTOP and SIGCONT, much like hitting Ctrl+Z on the console and later running bg <pid> or fg <pid>. Note that this is not the same as Ctrl+S & Ctrl+Q on the console – that just pauses the output display not the process (though the process may subsequently pause if a buffer somewhere down the pipeline becomes full due to the terminal output pausing).

    Thanks.

    Yep, that's exactly how it's done :)

      Thought it would be, but I didn't want to state that more authoritatively as I'd not bothered checking the docs/source. And I'm lazy like that.
