Caching _ExplorerPtr causes slow Outlook shutdown

If I cache an _ExplorerPtr (obtained from Application::ActiveExplorer) in my
addin, Outlook takes significantly longer than normal to shutdown after
closing its GUI - and if Outlook is restarted before it has completely
shutdown, the new instance will abort with no warning (though it will call
IDTExtensibility2::OnBeginShutdown and IDTExtensibility2::OnDisconnection,
but not IDTExtensibility2::OnConnection). Is this a known bug, or a problem
with my code? (I have written a test addin using the VS.Net Addin Wizard,
and it appears to exhibit the same behaviour as my addin).
 
Do you track the Explorer::Close event (where you must dereference the
explorer)?
