random.m: little warning

[Martin Stein]

Hi,

The random generator in random.m ran in a cycle of around 60 starting with seed 680380.
There are several other seeds with yields in very bad behaviour of my treap, too.
(It needs some time to find out that it was "only" the random generator.)

Anyway, are you interested in a hopefully better generator? I implemented one
using the Haskell Random.hs as a basis. But I still ought to check it a little.
