The third and fourth & fifth sentences: a) are hardly tacit agreement; b) show a profound misunderstanding about the way threads works.

There are no "copies" of shared variables, only aliases to them.

Threads do not emulate fork (*). There is no attempt to have the spawned thread continue from the fork point of the parent.

(*)Though they can be used to do so.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
