Does Tor Browser continue checking for further updates in the span of
time between when it downloads an update and when it is restarted? For
example, you are running 6.0, the browser downloads the 6.0.1 update and
stages it and asks you to restart; does the browser check for updates
until you actually restart? If not, then the decreases in update pings
might be people being tardy in restarting their browser.
