Is this change a temporary workaround until subprocess is fixed on VxWorks, or is this skip supposed to be a temporary workaround?

If it's a temporary workaround, I am not sure if it's a good idea to document the skip.

os.popen() runs cmd in shell, i.e. shell=True was set when calling subprocess.Popen(). VxWorks has no user space shell provided so that we can't create a new shell and run commands inside. For the subprocess module, VxWorks can't support features needing shell to run. So when I created this PR, I don't intend to be a temporary workaround.
