It seems they should always be flushed. certainly if a program fails via
'fail' in IO or 'error' as these are common ways for programs to report
an error and losing output would definitly be counter intuitive and make
it quite tricky to debug. especially when you can't flush stdout before
calling error. I would think it should flush all buffers on any type of
exit.
On a another note relating to errors, when profiling is turned on and
you write any profiling data out, programs always return a 'success'
error code no matter how they quit. It would also be nice to get partial
profiling data if one aborts the program early with ^C.
