I'm not oppose to use with (far from it I greatly prefer it.), however the with statement was firstly supported in Python 2.5: https://docs.python.org/3.6/whatsnew/2.5.html#what-s-new-in-python-2-5

This mean that you drop python 2.4 or former, in this point I have no objections because it was already unsupported.

If you use Python 2.5 or later, you can use 'file()' instead of 'open()'. Furthermore, FILE object returned by 'file()' (or 'open()') supports 'iterator' and you have no need to call '.readlines()' anymore, thus:

```

•        with file(filename, "r") as f:
  

•            for line in f:
  

... ```

      except IOError:
          return None

•    try:
  

•        for line in f.readlines():
  

•            if line[:9] == "owner_pid":
  

•                return int(line.split(':')[1].strip())
  

•    finally:
  

•        f.close()
      return None
  
  def get_pid_cmdline(self, pid):
      try:
  

•        f = open("/proc/%d/cmdline" % pid, "r")
  

•        with open("/proc/%d/cmdline" % pid, "r") as f:
  

•            cmdline = f.read()
      except IOError:
          return None
  

•    try:
  

•        cmdline = f.read()
  

•    finally:
  

•        f.close()
      return cmdline.replace('\x00', ' ').strip()
