Actually, now that I've moved onto testing cross-platform... On my mac, I get ThreadedSeedGenerator output that is compressible to ~10% of its original size... Which unfortunately means it's almost worthless as a source of entropy on that platform... On centos6 I got compressed to 26% ... Basically, the output is very inconsistent as a source of entropy. Anybody who wants to test or observe this, especially on other platforms, please give it a try. Simply launch the Test project. (It's not actually a unit test; it's a console project that runs a bunch of tests and displays results to Console.) http://www.tinhatrandom.org This is all in the very latest Master, which I just committed a few minutes ago, so you'll have to checkout source and build yourself. Alternatively, you could just use ThreadedSeedGenerator to collect a big blob of data (say, 8KB) and then see if it's compressible or not.
