Looks like queueing JS callbacks in not sufficient because Database threads currently get terminated on navigation and may therefore not have time to schedule their callbacks: 1 0x7243d44e1 WTF::MessageQueue<WebCore::DatabaseTask>::kill() 2 0x7243d0ac4 WebCore::DatabaseThread::requestTermination(WebCore::DatabaseTaskSynchronizer*) 3 0x7243d0988 WebCore::DatabaseContext::stopDatabases(WebCore::DatabaseTaskSynchronizer*) 4 0x7243d2be3 WebCore::DatabaseManager::stopDatabases(WebCore::Document&, WebCore::DatabaseTaskSynchronizer*) 5 0x7256d2e39 WebCore::FrameLoader::stopLoading(WebCore::UnloadEventPolicy)

Comment on attachment 382095 [details] Patch r=me Pretty sure WebDatabase is fully disabled these days, so I guess this is an example of why it would be good to remove the code entirely soon.
