Comment (by rwbarton):

 Okay, I tried running it under strace: the `write` from `hPutStrLn` is
 failing with `EIO`, which then gets turned into an exception, meaning
 `throwTo tid ExitSuccess` is never run. Since signals are handled in a new
 thread, if the signal handler raises an exception, it is reported to
 stderr (which, in this case, also fails with `EIO`), and the program
 continues to run.
