    Windows: Avoid deadlock in invalidation path
    
    During data version invalidation the AFS redirector must CcPurge
    any non-dirty extents on a file. This operation can be intercepted
    by a filter driver which in turn might open the file and close it
    again before the CcPurge completes.
    
    The AFSPerformObjectInvalidate call holds the ExtentsResource
    shared which can deadlock if AFSClose attempts an extent tear down
    which requires exclusive access to the ExtentsResource.
