I have a little model of a server below. The server handles all exceptions, and restarts itself after some errors. It also handles break?, to actually exit when requested.
While this server is running, if I press Ctrl+C before `(error 'foo)` is handled, the server exits correctly with 120. However, if I press Ctrl+C after `(error 'foo)` is handled, the `exn:break?` handler is never called, the server no longer responds to `Ctrl+C`, and (in this example) it eventually exits with status `1`. I cannot figure out why. As far as I can tell, this should always handle `Ctrl+C` by exiting with 120. > #lang racket/base > > (let loop ([n 0]) > (with-handlers ([exn:break?
