That can happen if the user calls revert explicitly as well (yes, less
likely and less severe, but still: the user might do M-x revert-buffer,
then get annoyed that it doesn't see the result, so do it again and again
and again).

It shouldn't be too difficult to protect against it by detecting the
situation and "reacting appropriately".
