To reproduce, start up simulator, and start up REPL and let simulator be discovered. Now quit simulator and try to connect. You will see that exceptions are printed but the cljs.repl code will move and try to call -load
At this point the REPL is useless, but the prompt comes up, instead of it exiting as it did previously. This appears to be the result of repl-caught not re-throwing. Perhaps we can simply use this hook to define a new handler so that a throw from -setup will cause REPL startup termination.
