Map hangs if Internet drops out

[e100]

If Internet connection is disrupted when the map is updating it can hang forever.
The default timeout with urllib is no timeout.
Apparently the only way to set it is to set the default socket timeout like:
socket.setdefaulttimeout(30)
Seems like it would be a good idea to set the default timeout in all code that makes requests using urllib to prevent this hang.

Great catch. I never would have considered that. I'll test it out shortly.

I added timeout option to urlopen and so far that seems to have prevented any hangs:

content = urllib.request.urlopen(url, timeout=30 ).read()

Thank Eric, I'll incorporate your change in my development unit.
