Interesting, I've never touched debug trap, this gives me a glimpse of
how it is working.

And as for the topic in general, I've had a moment of understanding
that what's needed is basically: a `stdbuf` command that's *built-in*,
and this comes down  to your idea of `STTY=… my-cmd` -like
inline-export variable, which is a nicer, more integrated version of a
stdbuf-clone builtin (and could be made non-only-inline-export, to set
once and forget). Now, who has time to look at stdbuf.c? :) To grasp
what the LD-trick used there is?
