The attached patch (against 20160330) addresses the issue for me on Linux; it has not been tested on other platforms. It adds the GRND_NONBLOCK flag to the getrandom() call and sends the appropriate failure return if it returns due to lack of entropy. The enclosing functions fall back to reading from /dev/urandom in this case.

Affected files:

Python/random.c - changes to py_getrandom()
configure.ac and pyconfig.h.in - look for linux/random.h for inclusion

Can this, or something similar, be considered for integration with mainline?
