Writing directly to /dev/tty is indeed wrong thing to do.

Eh? I do not understand this part at all. It does not seem to be related
to the problem at all.

Can't we rather rename the FILE * to 'out' or similar, naming it tty_fp
when it does not point to tty is kind of confusing.
Also we can simply do FILE *out = stdout; If we reopen it by it's file
descriptior we will end up with two different file objects, each of them
will buffer data and we will end up with messed output when something
will write to stdout and not the one we created.
