  * anyone logged in on the machine as user N, since this would enable
  * the superuser on the machine to sneak in and make use of anyone's
  * authentication info, even that which is only accidentally left
  * behind when someone leaves a public workstation.
  *
  * AFS doesn't use the unix uid for anything except

 /*------------------------------------------------------------------------
  * EXPORTED afs_Analyze
  *
  * Description:
  *     Analyze the outcome of an RPC operation, taking whatever support
  *     actions are necessary.
  *
  * Arguments:
  *     aconn : Ptr to the relevant connection on which the call was made.
  *     acode : The return code experienced by the RPC.
  *     afid  : The FID of the file involved in the action.  This argument
  *             may be null if none was involved.
  *     areq  : The request record associated with this operation.
  *      op    : which RPC we are analyzing.
  *      cellp : pointer to a cell struct.  Must provide either fid or cell.
  *
  * Returns:
  *     Non-zero value if the related RPC operation should be retried,
  *     zero otherwise.
  *
  * Environment:
  *     This routine is typically called in a do-while loop, causing the
  *     embedded RPC operation to be called repeatedly if appropriate
  *     until whatever error condition (if any) is intolerable.
  *
  * Side Effects:
  *     As advertised.
  *
  * NOTE:
  *     The retry return value is used by afs_StoreAllSegments to determine
  *     if this is a temporary or permanent error.
