That's certainly another option, although I would think it's about the same
amount of pain to the programmer (you need to do your own formatting and
length determination in either case - both calls just take a buffer and
length).  Also, you can't redirect the output of Vio calls to a file, so if if
the process was ever run detached or in the background you wouldn't be able to
catch exit messages.
