These two revisions:

Caused an api failure for: WKHTTPCookieStoreWithoutProcessPool
This was occurring on all platforms.

Alex, do you know why this would have caused a timeout?

Ha!  I think the problem may be that WKWebView.UIDelegate is a weak pointer and that CookieUIDelegate no longer leaks (and is deallocated at the end of its block), such that the UIDelegate callback never happens and the test times out.

We probably just need a place to assign the CookieUIDelegate so that it's not marked as a leak and not released before the end of the test.

[David Kilzer (:ddkilzer)]

I didn't notice this before, but WebKit2.WKHTTPCookieStoreWithoutProcessPool also leaks two WKWebView objects.

Note the FIXME here.  I don't understand why setting webView to nil here causes the next test to fail.  Seems like a real bug.
