I wouldn't think that would make a difference, as long as the
flush/close for the request always occurs at the end of the request.
The 4.0.3 hessian did change the i/o handling, because of the URL
disconnect() that I'd added for testing purposes (the 4.0.3 change
generalized the http connection and made it pluggable.) It's possible
the disconnect() was causing problems, which might not be a problem in
the new version.
