However, my experience is that the implementation I submitted works just fine. I don't think it is obvious that your implementation has better performance. One might argue that the cost for setting up an asynchronous exception handler is (at least) as high as the cost of forkIO, but I don't really know. In any case, my guess is that the actual performance difference is negligible for all practical purposes.
The difference was quite large in very concurrent situations when I did benchmarking earlier between my two implementations - also note that parIO in your case has the exception handler too. Just would like to get it right so real-world code would not have to re-implement it. - Einar Karttunen
