You mean before /usr is mounted? The only way /usr would not be mounted when
cleaning /var/run is if /usr was an NFS filesystem. If for some reason you
wanted /var on an nfs partition, it also would not be available [I am sure
that /var would be badly broken as an NFS partition].
BTW, before anybody suggests it, 'mount -a -t nfs' cannot be moved before the
call to /etc/rc.network. The call to rc.network cannot be moved before the
cleaning of /var/run (rc.network can populate /var/run with files depending on
options). However: there is a call to vnconfig (in /usr/sbin) before NFS
partitions are mounted [/usr can already cause problems if it is from NFS].
Solution: I don't have one, but if you are going to argue that 'find' isn't
available at the time /var/run is cleaned, neither is 'vnconfig'.
$ egrep -b vnconfig\|/var/run\|find\|mount /etc/rc

Real Programs don't use shared text. Otherwise, how can they use
functions for scratch space after they are finished calling them?
