It is perfectly legal to clear /var/run across reboots. Below is a bug from a user that ran into some trouble because an init script assumes that /var/run/package/ exists for its PID file:
http://bugs.gentoo.org/show_bug.cgi?id=332397 A quick grep through the tree shows 73 packages that keepdirs /var/run/package/. Perhaps not all of them are bugs but they are certainly redundant. A mass bug-filing is probably not the correct thing to do but perhaps we should document somewhere (devmanual?) that keepdir'ing a temp location should be avoided.
