SafariDriver occasionally times out when loading a page

[juliemr]

Using browser.get on SafariDriver occasionally (<1%) causes a timeout (this manifests as a message 'Timed out waiting for page to load').

So far, I have only observed this when running on SauceLabs.

As of Safari 10, SafariDriver is now shipped by Apple with Safari (see the post at https://webkit.org/blog/6900/webdriver-support-in-safari-10/). I'm closing old external safari issues because they are now obsolete.
