some exception context classes appear to be missing toString

Specifically com.joyent.manta.org.apache.http.impl.execchain.ConnectionHolder@1ee8b444 and com.joyent.manta.org.apache.http.params.BasicHttpParams@7880feac could probably be more useful.

You will probably have to make a custom method that pulls apart the properties and uses a ToStringBuilder to extract the properties of the ConnectionHolder and BasicHttpParams classes.
