Trying to streamline the URL retrieval example in the concurrent.futures docs were severely hampered by the fact the URLError thrown by urlopen doesn't tell you *what URL* it was trying to retrieve when it failed.

This is OK in synchronous code (where you probably still have the URL around), but quite a pain in asynchronous code (such as that using concurrent.futures) where the original context may have been lost by the time the future is signalled.

The URLError changes gone in as part of fix for issue10836 should give e.filename and e.reason.
