That would do nothing to prevent slowness of the cold requests, which
already run for 5s when completely cold.

In fact, unless done right, it would actually slow things down, as
lines would not necessarily show up as they're ready.

That's entirely inefficient.  It'll probably take hours or days to
pre-cache all the html pages with a naive wget and the list of all the
files.  Not a solution at all.

(0.5s x 35k files = 5 hours for log/blame, plus another 5h of cpu time
for blame/log)

The concept for git-arr looks interesting, but it has neither blame
nor log, so, it's kinda pointless, because the whole thing that's slow
is exactly blame and log.

There has to be some way to improve these matters.  Noone wants to
wait 5 seconds until a page is generated, we're not running enterprise
software here, latency is important!
