Greg -- is that something Mercurial could retry automatically?  Is this likely a network issue during the download, or something fixable?

This is something we can pave over in `hg robustcheckout`. Underlying issue is likely network flakiness. Of course, this will require this Windows task to use `hg robustcheckout`.
