Yes, this is a Thin bug/feature. You can adjust timeout value in
bin/deltacloudd:

101: argv_opts << ['--timeout', '360' ]

Value is set in seconds. Also please keep in mind, that in case you want to
fetch *all* amazon images, you will get ~ 5900 images, which is quite long
list ;-)

I want also open new discussion here at this point. I want ask you, what
should we return in /api/images call in EC2 driver.
There are some possibilities:

1) Images owned by current user (+ preserve owner_id param)
2) Images owned by amazon
3) All available images
