Here's a patch adding O_CLOEXEC to the os module, with test. This patch makes it possible to open and set a FD CLOEXEC atomically. O_CLOEXEC is part of POSIX.1-2008, supported by the Linux kernel since 2.6.23 and has been committed recently to FreeBSD. Note that I'm not sure that adding this flag to built-in open() is necessarily a good idea, because it's not portable and low-level. The same functionality can be more or less achieved with: f = os.fdopen(os.open('/etc/fstab', os.O_RDONLY\|os.O_CLOEXEC))
