Dave, I believe you misunderstood. This is not actually a cron
replacement. Instead, it allows you to trigger actions on filesystem
modifications. E.g. we could get rid of all the ugly
gtk-update-icon-cache calls in package %posts and instead have incron
monitor /usr/share/icons/* and trigger the icon cache update in that
way.
