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!
