note: it appears that hosts that don't exist (DNS failure) are loadbalanced 
fine on Windows, but cause the tests to fail (specifically 
TestDistributedSearch) on at least Ubuntu.  Looking into it...

update: looks like the issue was down to the DNS provider returning a 302 
Found and an actual response for the bad host.  If I add a .com to the bad 
host, everything starts working again.  That's what I've done for now.

Another big question is: can we use LBHttpSolrServer for this, or are the needs 
too different?

Some of the issues:
 - need control over order (so same server will be used in a single request)
 - if we have a big cluster (100 shards), we don't want every node or every 
core to have 100 background threads checking liveness
 - one request may want to hit addresses [A,B] while another may want [A,B,C] - 
a single LBHttpSolrServer can't currently do both at once, and separate 
instances wouldn't share liveness info.

One way: have many LBHttpSolrServer instances (one per shard group) but have 
them share certain things like the liveness of a shard and the background 
cleaning threads

Another way: have a single static LBHttpSolrServer instance that's shared for 
all requests, with an extra method that allows passing of a list of addresses 
on a per-request basis.
