Still going!

Sorry again for the repeated and long delays; the last two years have 
been eventful in other areas.

As you may have seen, I've just recently pushed a large changeset 
primarily addressing performance tuning in BigDecimal [1].  With some 
other large reviews I have oustanding and JavaOne, etc., I think I 
should be able to have your BigInteger patches integrated into JDK 8 by 
the end of the year.

After the changes are in JDK 8, it is possible for them to be backported 
to the JDK 7 update train.
