[issue26839] Python 3.5 running on Linux kernel 3.17+ can block at startup or on importing the random module on getrandom()

Stefan Krah: "I think this is a very good idea. Just a flag for "cryptographically secure" or not."

If you consider it is worth it, please open a new issue.

I dislike the idea of a boolean. The quality of each system RNG has been discussed long enough to be able to say that "cryptographically secure" term depends a lot of your use case, and experts disagree between themself :-) You might even have to consider the version of the Linux kernel to decide if /dev/urandom is good enough or not for you use case. The implementation changed last years.
