I've just observed the same failure with the looping code. I'm not sure
what is wrong. I suppose there is a window during the creation process
where the file exists, so the create fails, but the memory is not yet
ready, so the attach also fails. If one process is in this state
another process might loop around 10 times and have both create and
attach fail. Perhaps a short and/or random delay would help?
