gethostby*() calls a dispatch routine to "backend" functions that
implement the various methods.
The questions are:
* How does gethostby*()'s DNS back-end know to re-read resolv.conf?
I.e. how does it get the timestamp information about the resolv.conf
file for comparisons?
* Does the user have to do something silly like touch a file
unrelated to resolv.conf to trigger the reread?
