instances via global references...if an existing store is used then its stats
are retrieved.
Switching stats assertions to IOStatistics on the instance

> Intermittent failure of ITestHuge* upload tests, when doing parallel test
> runs.
> The count of bytes uploaded through StorageStatistics isn't updated. Maybe
> the expected counter isn't updated, and somehow in a parallel run with
> recycled FS instances/set up directory structure this surfaces the way it
> doesn't in a single test run.
