Hi Darrell, thanks for the patch.

Can you add a sentence or two to the commit message, please, explaining
the motivation or the goal for the patch?  It's not clear to me whether
this is a performance optimization, or a cleanup, or a fix for a race,
etc.  This information helps review the patch and it also helps people
looking through the history tracking down a bug etc.
