   Using thread-safe wrapper over EvictingQueue makes life simpler, however it 
does not have any perf improvement because earlier I was using lock to write 
data in array in thread safe manner (tested both with same load where both 
approach took ~20-22 s to complete). However, using it has good advantages over 
not losing any writes specifically if manual locks time out or get 
InterruptedException, and of course less manual code to maintain. Thanks 
@bharathv for the suggestion.
