resolv.conf changes and nscd

[John Fremlin]

When resolv.conf changes (for example, because you connected to a
different ISP) nscd never becomes aware of it. This is a general
problem with all applications using the libc resolver interface. 

It could be fixed by adding a field to struct __res_state with the
last timestamp of the /etc/resolv.conf file, which would be checked
with stat every gethostby* call. This would cause a syscall of
overhead.

Would such a patch be accepted? Or is there a better solution?
