You mean it should be created with EXCL?
Maybe.  Then again, AFAIK this is only used for debugging purposes, so
I'm not sure it's that important and you could assume that the user will
normally specify a file in a directory she owns, where the attacker
shouldn't be able to place a surreptitious symlink.
