Comment:

 Daira and I decided that it'd be slightly easier to fix this by dodging
 the bug: modify iputil.py (and other code that uses subprocess) to check
 for the existence of the executable before allowing `subprocess.Popen` to
 try and run it. This seems to work, and avoids adding a new dependency.
 I'll file a PR with this change in a moment. Hopefully this will tide us
 over until 1.11 is released, and we can switch to a whole new way of
 managing local IP addresses (probably by having the Introducer tell us, or
 requiring server admins to configure them explicitly).
