For serious simulations you want to publish repeatable results,
_independent_ of the Common Lisp implementation you use---In that case
your simulation program cannot depend on a package which calls CL:RANDOM
[as different implementations will produce different sequences of
numbers].  It is preferable to use FFI to a "Standard" C implementation,
like the "RANLIB.C" package from NETLIB,

In SBCL the random function uses the well known algorithm of Mersenne
Twister.
