>> The current behavior is that Python *will not start at all* if getrandom() blocks (because the hash secret initialization fails).
> It starts jsut fine, it just can possible takes awhile.

In my experience, connecting to a VM using SSH with low entropy can take longer than 1 minute. As an user, I considered that the host was down. Longer than 1 minute is simply too long.

It's unclear to me if getrandom() can succeed (return random bytes) on embedded devices without hardware RNG. Can it take longer than 1 minute?

Is it possible that getrandom() simply blocks forever?
