Aye.  Given the obviousl lengths that UOL players went to
empirically calculate and then graph the stat and result curves of
UOL (there are hundreds of K of carefully tabulated results on the
web), yes, this is important.

Rephrasing:  It is imperitive that the relationship between the seed 
value and the result of the rand() not be even slightly predictable.
