In general I'd argue for not just catching exceptions broadly as a defense.
This is a `stop()` method though, and often the right behavior is to just keep
going even if stopping failed due to some I/O problem or messed up state. Here
I don't see what exception this method can throw. I'd still find `try-catch`
surprising and would not expect it.
