Senders are pretty cheap (though there is a roundtrip or two on setup), 
so another workaround is to create a distinct Sender object for each 
thread. As far as the transfers on the wire go, for 0-10 at least there 
will be little difference.

The request doesn't require much in the way of power :) By all means 
create a JIRA - assign to me for now so it doesn't get 'lost' and I'll 
do my best to get to it, though I can't make any promises regarding 
timing yet.
