I think the file can be removed. I'll do that in R16B.

I agree that the return value of file:close/1 should be tested. Of
some reason it has been practice not to do it, probably because it
"always" returns 'ok'. There are hundreds of calls to file:close/1 in
Erlang/OTP, and just a few of them test the return value. Maybe it'd be
easier to fix them all at once. I'll put it on the to-do list.
