The buildbots are complaining about some of tests for the new socket.sendmsg/recvmsg added by issue #6560 for *nix platforms that provide CMSG_LEN. http://www.python.org/dev/buildbot/all/builders/AMD64%20Snow%20Leopard%202%203.x/builds/831/steps/test/logs/stdio Before I start trying to figure this out without a Mac to test on, are any of the devs that actually use Mac OS X seeing the failure in their local builds?
