Comment(by fperrad):
Random PMC is a wrapper over C rand48 funtions (pseudo-random generator).
These functions could be rewrite in PIR, like mt19997 (Mersenne Twisted)
were.
mt19997 and rand48 have not the same properties. See
http://en.wikipedia.org/wiki/Mersenne_twister .
Parrot could have many different pseudo-random generator libraries
(written in PIR).
But Parrot needs a portable entropy source, because /dev/rnd is only
available on *nix.
Perl5 Doc gives as advice : srand (time ^ $$ ^ unpack "%L*", `ps axww |
gzip -f`);
Parrot could do better (and simpler).
