With regard to Chris Kent's problems with buffered sdtout, we too
have noticed this problem.  In fact, one of my colleagues had a
problem with his printf's not printf'ing, so I wrote a short hack to
test his use of printf and gets.  Mine worked fine, but his still
failed.  We scratched our heads until we noticed that stdout's
buffer is flushed on a call to fflush(stdout), when it gets full,
or WHEN STDIN IS READ(!).  Simple when you know the trix, isn't it?
