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

A library RNG should probably accept its place in the universe as a thing that will get forked and rather than trying to second guess the system it should instead either mix in new entropy on every call or should direct the programmer to use more effective resources (operating system RNG service, instruction set RNG, etc.).

I don't think a linkable library is really the right place for an RNG. It's fine for providing a conservative way to access system entropy, but not fine for operating in isolation and a CSPRNG.
