Your patch doesn't fix the things Tom referenced (nor did you intend  
it to). I just wanted to to collect examples of all the known issues  
with the interval code in one place. Probably too ambitious for  
September 1.

Is it worth looking into the overflow and subtraction issues for 8.2?  
It seems to me they're bugs rather than features. Or are these 8.3  
since it's so late?
