Uhm... does that even exist in kernel trunk yet? That's pretty amazingly new. I would guess Python doesn't want to start using something like that until it's *at least* appeared in a released kernel; although of course you're welcome to run a patched Python on a patched Linux to make use of this. Trouble with that seems to be that it's reducing code paths from two to... two. Instead of having a seldom-used code path for the fall-back when there's no fd available, you instead have an alternate code path for the fall-back when getrandom() doesn't exist. But if the Linux guys decide to implement this, then you can take it to python-dev with "This is supported by Linux 3.x.y" (or probably "Linux 3.x"), and preferably a patch that includes something in ./configure to probe for availability. Patches speak louder than words :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
