Yes, but there is a small quirk in the gen_server.erl module that
causes it not to heed the shutdown protocol if started with
gen_server:start(), even if you _do_ create the link in some other
way. From the supervisor side, everything is fine, but the gen_server
doesn't recognise the supervisor as its parent.

So, when the child is a gen_server, the start function must be
{gen_server, start_link, [...]} in order for everything to
work correctly.

The same goes for gen_fsm and gen_event.
