This doesn't make any sense to me. CURLOPT_DNS_USE_GLOBAL_CACHE defaults to
zero so you setting it to zero or not setting it at all will have the same
effect. libcurl only uses a global dns cache if you explicitly tell it to. Any
other way would cause serious breakage when used by apps all over.

That indiciates the problem is already before SSL (NSS) gets involved.

What Linux version and platform and libc is this running on? It seems "fishy"
