--- Comment #5 from Brady Eidson <beidson at apple.com> ---
The event handler in question is as follows:
        event.target.transaction.oncomplete = function() {
            window.webkit.messageHandlers.testHandler.postMessage('Transaction complete');
        }

~95% of the time, that message never gets back to native code.
Sometimes it does.

If I change it to the following:
        sawTransactionComplete = false;
        event.target.transaction.oncomplete = function() {
            window.webkit.messageHandlers.testHandler.postMessage('Transaction complete');
            sawTransactionComplete = true;
        }

... and then pass the value of sawTransactionComplete through to the onsuccess event handler message, native code sees that sawTransactionComplete is in fact true.

If I change it to the following:

        event.target.transaction.oncomplete = function() {
            window.webkit.messageHandlers.testHandler.postMessage('Transaction complete');
            alert("Made it here!");
        }

Then the existence of that alert() call makes the test reliably pass!
