Well, after you call MHD_stop_daemon(), we're definitively done ;-).

But yes, you are totally right in the rest of your analysis.

Well, that's because you can share the same response object across
multiple connections, in which case the completed callback for one
connection is not helpful for the next one.  Otherwise, yes, this ought
to be safe, but as you said, this is not how PERSISTENT is supposed to
be used.
