Another thing we may change in Ajp13Interceptor.java, is
setSoLinger() which could delays too much connections close.
cf: bug regarding apache threads against ajp13 threads....

> Bug fix - under certain conditions the POST data was messed up. This
> doesn't happen with browsers, but it did happened with the
>test application,
> because the body was sent in a different tcp packet. We do receive a
> body packet just after the headers ( we could delay that -
>in ajp14 ), and
