Defer conn free until the exit code of topmost callback functions, for both parent and child connections, this is necessary to handle error conditions correctly and terminate connections gracefully
...
So introduce term flags in ctx and replace free functions with term functions to raise the term flag, this approach enables us to terminate connection anywhere in the code without causing use after free crashes
