Of course. I'm not gonna kill reachable modules like a cowboy on the
loose :-)
The problem is that its global objects will get finalized very late.

Anyway, the solution is to unpatch builtins through an atexit handler
in the site module.

(my patch still has a last step where surviving modules get their
globals wiped, though)
