Threading in LBHttpSolrServer

I think we have to take another look at the thread safety in 
LBHttpSolrServer. At a minimum it appears to be using double-checked 
locking with aliveCheckExecutor? I'll look closer later, but I think 
there are a couple issues.

You are right. The executor should be volatile.
