Hi Jiutao, it is important to keep improving the JIT and good to see
that you are interested.  There are still one or two people around who
'look after' the JIT code, and I'm sure they will be delighted to work
with you to implement the improvements.

It's true that there has not been as much activity around that area of
code, which might make it slow to get your proposed improvements
reviewed and accepted.  On the other hand, it means you are more likely
to get commit status more easily by working with the community and
producing valuable work in that area!
