    I had just queried Joe Darcy at Sun about reviewing my patches for 
Karatsuba and Toom-Cook multiplication in BigInteger again last week. 
His reply was:

    "Yes, I apologize again for the repeated delays; I want to get your 
Karatsuba work reviewed and integrated within this JDK 7 milestone (the 
next few weeks)."

     So I'm hopeful.  So far, I haven't heard of any substantive issues 
with the patches.  They were mostly stylistic.

     As I've stated before, I also have patches that greatly improve the 
performance of pow() and toString() (by orders of magnitude) that I have 
been holding on to for a long time, and hoping to submit after the 
multiplication patches are approved.  (I was asked by Joe Darcy to 
submit in smaller patches.)  Hopefully these might get in JDK 7 too.
