This reverts commit 3f4d8cbe.

this fixes a regression when a final name has a dependency with a short
TTL in the search path, but has longer TTL itself
in another words - if there's a CDN in the middle and the name doesn't
exist, answer it from the cache without requerying the CDN

this saves space for both library and daemon

this allows for continuation of a function in the background,
a good use case for this is loading of chunks of data or I/O 

This reverts commit 3d1ee641.

This reverts commit ee2cce4d.

previously only queried names were resolved from cache, this meant that if the target name was present in cache but a server on the search path dropped from it, it would refetch it - this is a problem when a loadbalancer with very short TTL was in search path

if the flag is left on, it prevents further caching
