Description

Disable caching of failed DNS lookups. This is causing problems on network changes, since we don't have a reliable signal for telling when DNS is back up (so we aren't able to flush the cache properly). This will regress bug 1672, filed 46821 to address that. BUG=46821 Committed: http://src.chromium.org/viewvc/chrome?view=rev&revision=50141

Yes, this will hurt performance for certain cases. The most notable one is 46821
(which can mean the difference between say a 2 second load time versus a 30
second load time).
