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. Suggestion:

+<title>Invalid use of <c>keepdir</c>in src_install</title>
+<body>
+The <c>keepdir</c> function should only be used to prevent directory removal
+during uninstallation. In particular, using <c>keepdir</c> for a temporary
+location - such as /var/run/package/ for a PID file - should be avoided. In
+such a case, init script either should make sure that /var/run/package/ exists
+or the package should use /var/run directly. Please note that /var/run can and
+will be cleaned across reboots.
