It could give me back the name I opened it under, or "stdin", "stdout",
or "stderr".  That would be a lot better than nothing.  I currently
accomplish this for my own systems by redefining Unix library calls
ie "#define open uxopen" and stashing the text string in uxopen.  But
I would sleep better if I didn't have to do such disgusting things.
