And who and what would change resolv.conf between off- and online,
and why is that necessary?

Is there sustainable evidence that resolv.conf changes between off- and
online?  Is really *stale* nameserver information cached inside libc or
in fetchmail's context on behalf of libc's or libresolv's code? If so,
it's still a libc/libresolv bug.

And unfortunately, neither using a documented interface nor is it
portable, so not suitable for the upstream.

It also requires linking with -lresolv according to my resolver(3)
manpage (SUSE 10.0 though, not Debian). This will be the case as long as
res_search is only in libresolv, but not in libc - just as a hint for
the packagers (Nico, Héctor).

Thank you for your information though.
