It may be able to use kqueue.  However, I'm not sure how kevent() is
cheap than stat().  It requires holding a file descriptor for
monitoring change of resolv.conf.  The logic will be slightly
complicate, and it may cause memory leak.  So, unless there is
significant advantage to use kqueue, stat() is better here, IMHO.

Sincerely,
