Thanks Paul. That definetly helps.. things run a good bit faster now. I've
made you a contributor and have assigned you this issue. I was a little
enthusiastic purging httpclient -- turns out its needed by stargate -- so I put
it back. Otherwise stuff seems to work fine w/o the others.

> From a discussion on IRC, the Maven assembly speed is pretty bad, this is
> likely due to http://jira.codehaus.org/browse/MASSEMBLY-424 (process fork per
> dependency, ouch).
> Slimming the dependency tree will not only make the generated assembly more
> compact, it can speed up the build process.
> Will attach patch to propose slimming the dependencies based on stacks
