Summary REGRESSION (Yosemite): HTTP tests time out waiting for subresources

On Yosemite only, I see some tests time out, apparently stalled waiting for Apache to respond. See e.g. <https://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fxmlhttprequest%2Fredirect-cross-origin-tripmine.html>

On the other hand, we have a high number of concurrent requests allowed, so this shouldn't be happening.

All the requests for xmlhttprequest/redirect-cross-origin-tripmine.html test show up as taking a small amount of time.
