Wouldn't this wreak havoc with libs that expect stdin/out to always
exist? Unix systems more typically freopen() the std file streams to
/dev/null, so libraries aren't so surprised. I think dos/windows has a
null device, too. Called "NUL:"?
The primary use of the freopen() function is to change the file
associated with a standard text stream (stderr, stdin, or stdout).
The fopen() and freopen() functions conform to ANSI X3.159-1989
freopen(3) on Linux
lua doesn't support freopen(), perhaps it should.
