Content
The future Linux kernel 3.17 will have a new getrandom() syscall which avoids the need of a file descriptor: http://lwn.net/Articles/606141/ The file descriptor of os.urandom() causes perfomance issues and surprising bugs: #18756, #21207. I don't know when the function will land in the libc. OpenBSD 5.6 (not released yet) will also have a new getentropy() syscall. For Python 2.7, see also the PEP 466 and the issue #21305.
