We've been seeing some of this:

2018-02-14 20:16:44,011 17816 CRITICAL BrozzlingThread:36444 brozzler.worker.BrozzlerWorker.brozzle_site(worker.py:559) unexpected exception
Traceback (most recent call last):

brozzler.browser.BrowsingTimeout: timed out after 11.1s waiting for: <function Browser.start.<locals>.<lambda> at 0x7fb2dc772bd8>

Mostly at startup. Now that brozzler claims sites in batches for
brozzling, we have situations where we start up a whole bunch of
browsers at the same time. That's probably why in some cases they are
slow to establish the websocket connection.
