Well,

1000000001 - 99999999 = 900000002
100000000 - 99999999 = 1
1000000099 - 999999999 = 100

Another clue: range() allocates the entire list before returning (you might 
prefer to use xrange() if appropriate).

Allocating a list containing 900000002 entries uses at least 3.6GB.  If 
your machine could handle this I'd be mightily impressed!
