def running?
  # A process is considered running if:
  # unix: it is in running(R) state or either of sleep state(D: Uninterruptible or S: Interruptible)
  # windows: it is responding i.e. state is True.

  # Other codes like <(high priorty), N(low priority), +(foreground process group) etc. may appear after the state code in unix.
  # Hence the regex used is /^statecode+/ where statecode is either R, S, or D.
