Good catch.

I might be wrong, but it looks to me like cl-random and Frandom are
currently both limited to small integers (< 31 bits and fixnum range,
respectively) and we don't have a random number generator that will do
the right thing for
(random 100000000000000000000000000000000000000000000)

Any idea how easy it would be to fix either of them, or both?
