    Windows: MergeStatus before SyncOpDone
    cm_SyncOp/cm_SyncOpDone is used to synchronize the RPC processing
    to ensure that calls which are in conflict cannot occur at the
    same time but also to ensure that the ordering of operations
    is consistent.  cm_MergeStatus() was in many cases executed after
    cm_SyncOpDone() removed the synchronization barrier which in turn
    permitted status information to be applied out of order.  Side
    effects could have included data loss due to client side file
    truncation.  More commonly two StoreData RPCs would have their
    status information applied out of order forcing the cache manager
    to invalidate all of the cached data for the file.
