'''
I wanted a quick way to spawn a bunch of Safari tabs with distinct favicons, so made a little webserver
to rotate through some PNGs. A substantially smaller program was sufficient for Chrome, which does what
I expect when I manually reload a page.
Safari loads the favicon once per window, regardless of the number of tabs or reload attempts, because
Safari assumes it's safe to re-use. An 'empty cache' yields one subsequent favicon load. More importantly,
Safari looks down at you for having the temerity to engage in what might be deemed 'wasteful' behavior by
trying to generate a bunch of 'useless' network traffic, so your commands are silently degraded.
Anywho, to get Safari to load a distinct favicon in each tab, it's not enough to advertise a unique favicon
name in the rel="icon" link, you also need each tab to use a unique request URI.
