    * lib/securerandom.rb (gen_random): to avoid blocking on Windows.
      On Windows OpenSSL RAND_bytes (underlying implementation is
      RAND_poll in crypto/rand/rand_win.c) may be blocked at
      NetStatisticsGet.
      https://wiki.openssl.org/index.php/Random_Numbers#Windows_Issues
      Instead of this, use Random.raw_seed directory (whose implementation
      CryptGenRandom is one of the source of
      entropy of RAND_poll on Windows).
      https://wiki.openssl.org/index.php/Random_Numbers
      Note: CryptGenRandom function is PRNG and doesn't check its entropy,
      so it won't block. [Bug #12139]
