DL 909

I agree with Sean that DL 909 is currentl flawed.
I prefer a small change over making it extra credit.

In particular I am pretty sure that the number which is currently 10 
billion was intended to be 1 billion (i.e. fitting within 31 bits).

I am happy to make this even smaller if for example WG members felt that 
more than 23 bits was unreasonable.

This number is used in the test to distinguish finite from infinite.
i.e. a set with cardinality of less than this number is known to be finite. 
However the number is sufficiently high that an exhaustive analysis of each 
possibility is unlikely to be practical.

We may at a later stage in the CR discover that no implementations are 
implementing such a distinction, hence we may choose to make this extra 
credit anyway, but for the more compelling reason that the heart of the 
test is hard, rather than the superficial reason that the test overflows a 
register somewhere.

Propose - modify test dl/909 to use 1 billion instead of 10 billion.
