My implementation of the PEP 433 uses accept4() for socket.accept() if the (new) cloexec parameter is True: http://hg.python.org/features/pep-433/file/46b7a077ae87/Modules/socketmodule.c#l1961 The code fallbacks to accept() if accept4() fails with ENOSYS. It happens if the glibc version is 2.10 or newer, whereas the Linux kernel is older than 2.6.28. I didn't test the fallback yet. I see in changeset 12442ac3f7dd (issue #7523) that SOCK_NONBLOCK is also set in the flags parameters of accept4(). I should probably also do that.
