That's what I was thinking of... I haven't tested this in a while (and 
don't feel like rebooting to test it now), but last time I set 
NETWORKING_IPV6=no resulted in IPV6 initialization not being performed, 
_BUT_ enough IPV6 initialization was done (possibly due to module 
autoloading?) to result in the ipv6 module loading (and that's enough for 
later programs to do pointless (in a non-IPV6 environment) IPv6 
queries/connects/sockets etc.)
