	I'll stop you there.
	Both libresolv and lwres assume a *STATIC*
/etc/resolv.conf. They read it once and use it for all subsequent
resolution. However, if the OS changes /etc/resolv.conf, this
assumption is plain invalid and need to be fixed.
	This is the bulk of my patch (dynamic_config). The rest is
only optional eye candy.
	That's the issue. Everybody assume it works, but nobody
bothered to check.

	I already explained what the problem where with these. But it
doesn't matter as none of this addresses the core issue (the static
versus dynamic issue).
