Comment (by ryandesign):

 Ok yes, with that in mind, I can reproduce the issue on my own machine:

 * disconnect network

 }}}

 I think the fix is in `proc _archive_available`, before it checks for an
 archive on the server, it should check if the archivefetch phase has been
 completed. If it has, it should return `no`.
