  // we initialize it as Rand() + 27437 instead of just Rand(), because on some
  // systems, e.g. at the very least Mac OSX Yosemite and later, it seems to be
  // the case that rand_r when initialized with rand() will give you the exact
  // same sequence of numbers that rand() will give if you keep calling rand()
  // after that initial call.  This can cause problems with repeated sequences.
  // For example if you initialize two RandomState structs one after the other
  // without calling rand() in between, they would give you the same sequence
  // offset by one (if we didn't have the "+ 27437" in the code).  27437 is just
  // a randomly chosen prime number.
  seed = Rand() + 27437;
