Original issue's description:
> Re-enable rate limiting for Windows Crashpad
> 
> Chrome can get itself into crash loops that cause massive numbers of
> uploads. We'd like to have UMA to see what we're dropping, but for
> the time being, mitigate by re-instituting the Mac-style 1/hr upload
> limit.
