Ingmar Runge provided a source snippet that caused a crash. The reason for
the crash was that libcurl internally was a bit confused about who owned the DNS cache at all times so if you created an easy handle that uses a shared DNS cache and added that to a multi handle it would crash. Now we keep more careful internal track of exactly what kind of DNS cache each easy handle uses: None, Private (allocated for and used only by this single handle), Shared (points to a cache held by a shared object), Global (points to the global cache) or Multi (points to the cache within the multi handle that is automatically shared between all easy handles that are added with private caches).
