How about _very_ long term to remove sysctl (i.e. January 2010)?

+What: sys_sysctl
+Date: January 2010
+Contact: Eric W. Biederman <ebiederm@xmission.com>
+Description:
+ sys_sysctl uses binary paths that have been found to be a major
+ pain to maintain and use. The interface in /proc/sys is now
+ the primary and what everyone uses.
+
+ Nothing has been using the binary sysctl interface for some time
+ time now so nothing should break if you disable sysctl syscall
+ support, and you kernel will get marginally smaller.
