> I think this impacts all of the code that uses asynclocalizer, but I need to check to be sure.
> As part of a review of a different pull request against AsyncLocalizer I noticed that requestDownloadTopologyBlobs is synchronized, but everything it does is async, but there is a race in one of the async pieces where we read from a map, and then try to update the map later, all outside of a lock.
