Curiously, there's two cron jobs, apparently.  There's a 'push' one and
then another, independent, 'pull' one.  I'll assume they're actually
doing different things, but I wonder if the pull isn't just a
hold-over..  In any case, the push-to-anon, which I hadn't seen
initially (looking at the pull side instead of the push side), does run
once a minute, though it looks like there's a hook mechanism which
would allow us to trigger the webserver to do a pull when a commit
happens and would still be better than a once-a-minute cronjob.

Even with that, however, the concern raised was that the gitweb perl
script is quite expensive to run for every request, hence the reason for
doing the cacheing.  I've lowered the varnish cacheing to a 5m ttl and
15m grace and I'll keep an eye on it.

	Thanks,

		Stephen
