You didn't give a clear answer to my question. Am I right in thinking
that your answer would be Yes, the GHC release should be delayed

We're happy to try to improve things, but I'm not sure what change you

Hi,
If a program throws an exception that will cause it to be terminated
(i.e. the exception isn't caught), will the code that prints out the
error message to stderr make sure to flush stderr before terminating
the process?
