See http://seclists.org/nmap-dev/2012/q4/334 for why this wasn't really a big problem. This solution is essentially how netcat-openbsd does it: mkstemp creates the file and opens it, but then we just unlink it and only use the returned name. Functionality is pretty much the same as the tempnam version.
