Punishingly expensive?
You have to remember that Python is an entire programming language with
its standard library, used by millions of people. That its test suite
can run on 4 minutes on a modern computer actually makes it rather
"fast" IMO (and, perhaps, incomplete...).

If you have a "push race", then after merging you could just re-run the
tests that are affected by your changes (of course, if you did a change
in the interpreter core, you probably should run the whole suite again).
That's both faster and better focussed than a hypothetical "smoke test".

(that assumes you did run the test suite before doing the original
commit, of course)
