[RCD] sessions started on connect?

Hey all, we use hardware loadbalancers that connect to apache to see if the server is still ok. It does not login.

I just realised these do actually create sessions, causing problems with garbage collection :(

select ip,count(ip) from session group by ip order by count desc;

              ip                    | count 

-----------------------------------------+------- 194.109.20.222 | 14321 194.109.20.221 | 14295 2001:888:0:22::4 | 4296 2001:888:0:22::3 | 4288

Are connects without login supposed to create a session? If so, why? This is with a relatively recent 0.7 from svn.
