Since r267608, many http tests, especially related to WebsiteDataStore, have been failing/timing out, triggering the bots to exit early. Sample build runs: GTK: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r267611%20(16057)/results.html WPE: https://build.webkit.org/results/WPE%20Linux%2064-bit%20Release%20(Tests)/r267611%20(20221)/results.html
r267608 was reverted. I'll check these failures to ensure the new patch doesn't break the tests.
