Oh yes, I quite agree, it would require a real change to
the Autoconf implementation, and people who write tests
would have to be disciplined about their dependencies.
The default would be sequential, for backward compatibility,
but if someone goes to the work to declaring their dependencies,
we could assume that it could be slotted into a make -j
or whatever.

None of this stuff would be a breeze, of course.

We'd have to stay sequential in limited environments like that.
That's OK.
