    Windows: Trend Micro QueryDirectory deadlock
    Trend Micro will deadlock both itself and the AFS redirector by
    calling a worker thread to generate a temporary file name during
    an active FindFirst Directory Query.  The Trend Micro worker will
    also attempt to enumerate the directory.   If the directory contains
    an entry for which the data version as reported by the service is
    different than the data version in the ObjectInformationCB a deadlock
    will occur on the matching FileCB Resource.
    To avoid this deadlock, prevent AFSValidateEntry from purging or
    updating the ObjectInformationCB and FileObject information when
    called from AFSQueryDirectory.
