------------------------------------
Awesome news guys... not using Jetty's writers did in fact result in
performance improvements!
This was a simple test that requested 500 docs per request (hitting all the
caches to try and isolate writer performance). Performance improvements of
almost 30% for XML!

> Some background here:
> http://www.lucidimagination.com/search/document/6babe83bd4a98b64/which_unicode_version_is_supported_with_lucene
> Some possible solutions:
> * wait and see if we get resolution on
> http://jira.codehaus.org/browse/JETTY-1340. To be honest, I am not even sure
> where jetty is being maintained (there is a separate jetty project at
> eclipse.org with another bugtracker, but the older releases are at codehaus).
> * include a patched version of jetty with correct utf-8, using that patch.
> * remove jetty and include a different container instead.
