[arch-dev-public] Cronjob for regular git garbage collection

When I broke our projects.archlinux.org vhost, I noticed that cloning git via http:// takes ages. This could be vastly improved by running a regular cronjob to 'git gc' all /srv/projects/git repositories. It would also speed up cloning/pulling via git://, as the "remote: compressing objects" stage will be much less work on the server. Are there any objections against setting this up?
