I agree that noticing such changes immediately is unreasonable,
but the resolver code could stat("/etc/resolv.conf") every now and
again and notice changes in st_dev or st_ino. It might as well
look at st_mtime and st_size at the same time, as a safety net in
case kqueue is broken or not available.
