I was thinking about using `dynamic-wind` but indeed was worried about
post-thunk being called multiple times. Wrapping with
`call-with-continuation-barrier` sounds like the right thing to do.
Additionally, the note from Matthias lead me to realize that
`call-with-exception-handler` is supposed to receive an actual thunk as its
second argument and `with-handlers` most definitely isn't one. Moving it
into a thunk resolved the problem so that means in my erroneous code
`with-handlers` was being evaluated before `call-with-exception-handler`
even has a chance to install the handler and see the raised exceptions.
Now I just have to think some more about which avenue I want to use.
Thank you for your suggestion!
