> It just occurred to me that we are dropping 0ms spans when we poll the
> sendQueue for a span to deliver via thrift. It would cause less churn in the
> queue if we dropped the span as soon as we received it, before inserting it
> into the queue.
> This is already fixed in 1.6.3 which no longer drops 0ms spans. It is only
> really a concern in 1.7.0 if you are using HDFS tracing, which generates a
> LOT of 0ms spans.
