It is ugly but it is simple :)  And it seems to work!

But when I tested it and I saw the error message (Bad file descriptor),
I became even ashamed of my question. For my specific requirments,
simply opening the file in "write" mode would be enough :)

  f = io.open("temp", "w")
  print(f:read())
  --> nil	Bad file descriptor	9

Anyway, thanks for all the suggestions; there were sereval interesting
stuff there (and this specific one that reminded me of that kind of
error.)
