What do you mean by "shell execution"?

What I had in mind was that we should synchronize PATH with exec-path
each time we invoke a subsidiary process, either through call-process
or start-process.

There could be an issue with async subprocesses that are already
running, though: they still use the old PATH, while Emacs will see the
new value.  This could lead to subtle bugs.

But we don't change PATH _in_ the cmd session, we change it _before_
the session begins.
