> Using one lens client to fire two queries in two threads results in
> discrepencies. LensClient has a {{Map<QueryHandle, LensStatement>}} and also
> has a cached instance of {{LensStatement}}. When two threads fire queries,
> both use the same statement object. {{LensStatement}} object in turn caches
> {{LensQuery}} Object. So whichever thread fired query last is the last one to
> set lens query inside statement causing
> {{LensClient.getStatement().getQuery()}} to return that query object for all
> threads.
