> In {{TabletServerBatchWriter.MutationWriter.queueMutations(...)}} (line 736), HTrace
{{Span}}'s are not properly propagated across thread boundaries.  Consequently, tracing doesn't
propagate into {{TabletServerBatchWriter.SendTask.send(...)}}, and so the {{sendMutation}}
event is not logged.
> This can cause {{ShellServerIT.trace(...)}} to fail.
