[issue18756] os.urandom() fails under high load

[Donald Stufft]

Donald Stufft added the comment:

Looking at random.SystemRandom it appears it would suffer from the same FD exhaustion problem.

So as of right now afaik none of the sources of cryptographically secure random in the python stdlib offer a way to open a persistent FD. The primary question on my mind is if os.urandom can't be modified to maintain a persistent FD can Python offer a urandom class that *will* maintain a persistent FD?
