I had a quick look, and the NSS service module compiled
--with-context-proxy is likely insecure (in the sense that it enables
local privilege escalation).  The reason is that NSS service modules
are loaded by many SUID binaries, and some of the getdns dependencies
(OpenSSL in particular) have not been designed for this scenario.
