/dev/urandom isn't a great test, IMO, simply because there are reasonable tradeoffs in security v speed.
For all I know BSD could be doing 31*last or something similar.
The algorithm is also free to change.

But that's also why the rng stuff was so much faster. There was a long period of time where the Linux dev in charge of randomness believed a lot of voodoo instead of actual security practices, and chose nonsense slow systems instead of well-researched fast ones. Linux has finally moved into the modern era, but there was a long period where the randomness features were far inferior to systems built by people with a security background.
(I was involved, somewhat peripherally, in OpenBSD security during the era of the big OpenBSD Security Audit).
Ultimately, they suffer from a lack of developer resources.
Which is a shame because it's a wonderfully integrated system (as opposed to the tattered quilt that is every Linux distro). But I suspect it's the project leadership that keeps more people away.
