<pre>The WebCore IconDatabase lives in the UI process. The WebContent process sends RetainIconForPageURL/ReleaseIconForPageURL messages to the UI process via WebIconDatabaseProxy. When a page is closed, its associated HistoryItems are released, which in turn queue ReleaseIconForPageURL messages for their URLs. However, the process terminates before the messages are actually sent to the UI process, so the WebCore IconDatabase is not able to balance the retain counts.</pre>
