The most general response to your request would appear to require violation
of the Halting Theorem.  I think you could force a dot with an interrupt,
but it wouldn't really tell you anything.  The program could still be hung.

As it is, the problem is even more complicated than what is contemplated by
the Halting Theorem, since an installer depends on expected responses from
hardware.  If the response never comes...

You could be getting dot dot dot, and it wouldn't mean a thing.  Sort of
like waiting for Godot.

If some poor soul at Microsoft couldn't deliver a version of Vista that
reassured Steve Ballmer (who allegedly throws furniture) that wonderful new
Vista was actually doing something while he sat there and waited with an
important customer, do you think this problem will be solved by the FOSS
