I don't think so.

When they are saying "the exec never returns", they are meaning that
from the POV of the programmer, the spawned thing never returns.

That's why you can do

do IO

However, in our case, when I say "exec never returns" I mean "exec()"
never returns.

so you'd never actually get to "do IO" above, because you are hanging in

Big difference, right?
