Not sure if it matters in any real-world scenario, but I found it pretty 
surprising while playing with it. It should be trivial to fix; ISTM the 
problem is that there is a "continue" in the loop when select() is 
interrupted by signal, but the re-opening is done after the select() in 
the loop. I think all you need to do is move the check for output_reopen 
to the beginning of the loop.
