OpenSSL kinda takes care of that. The PRNG mixes the PID into the seed so parent and child won't see the same output. The patch fixes a slightly more tricky issue: - parent initializes PRNG but never touches the PRNG again - parent forks lots of child processes - PIDs get reused -- two child processes with same PID get same pseudorandom data
