> According to [~jdere], ATSHook is currently accessing the PerfLogger on a
> separate thread, which means the main query thread can potentially write to
> the PerfLogger at the same time.
> The ATSHook should access the PerfLogger on the main query thread, before it
> sends the execution to the ATS Logger thread.
