We raised this question during the Random module review: do we need parSafe at all?
Pro: we want to keep Random in line with whatever solution the standard collections end up with.
Con: it is not obvious that parSafe is needed. For example, fillRandom and iterate ensure internally-concurrent operation safety without locking. If the user needs a parallel random stream, they can do their own locking.
