/*   With normal per-domain connection limits and a naive implementation, we
     won't ever be able to load all these videos because the first 15 (or whatever)
     will each take up one HTTP connection (which will be suspended) and then
     the others will be blocked by the per-domain HTTP connection limit. We
     pass this test by closing the connection for non-buffered videos after
     we've got the first frame.
