Is it really *likely* to fail? It's just a name, and it's opened in
'w' ('+b') mode, not 'r' mode. That is, it creates the file -- no
file of that name need already exist (and if one does, it tries to
overrwrite it). Running on Windows most days, I'm not usually aware
of all the permission bugs Linuxheads delight in torturing themselves
with <wink>.

+1. As you later discovered, this "hmm, let's try to guess what we're
doing based on obscure droppings" business is a continuing bug
factory.

I'm neutral on whether you try, but +1 on you actually doing it <wink>.
