Did you tcpdump it? I put the iijpp tcp/ip logging flag on, and watched the port 53 requests go across for an rlogin into myself. Given that it was a completely local connection that should have been handled over the loopback interface (I did use my host name, and not "localhost", however), it issuing reverse lookup requests for my machine instead of getting the data out of /etc/hosts is an error. This is compounded by the fact that I am using a non-routable network, so there's no way in hell a non-local resolver would be able to help me anyway. 8-(.
