This is just due to ignorance, Linux provides a AT_RANDOM auxv on process creation that could be used to seed the prng.

  look at the code. AT_RANDOM is. used when it's avaible in the fallback function. For some reason, the devs don't seem to trust it much, according to the comment.

    Is it guaranteed to at least be different for different processes? They could use that in addition to the PID test to know when to reseed.

      No. It's only filled on execve, not fork.
