LibreSSL's PRNG is Unsafe on Linux [Update: LibreSSL fork fix]

We really want to see linux provide the getentropy() syscall, which fixes all the mentioned issues. Requiring the consumers to fiddle with the PRNG is not a sustainable "solution".

/dev/*random has way more issues than just chroot. For one - what do you do in the fd exhaustion case?

And yes, there are no such issues natively on OpenBSD, since we do have getentropy and our PIDs are random, plus they don't get recycled quickly.
