Yes, that sounds about right.  IIRC, Marsaglia himself posted a correction
in some newsgroup.  But then, this deficiency is relevant only for a small
number of applications.  In the context of computer chess I do not expect
this to be of any relevance.  In cryptography the standards are much higher
than for simple monte carlo experiments.
