Comment:

 I wrote a test that shows the cache is accessed during downloads from a
 {{{NoNetworkGrid}}}.

 I initially tried a "break-the-servers" test as per the ticket
 description, but this fails when the client finds no available versions.
 This seems consistent with the goals expressed in #465, which mentions
 performance but not availability.
