OK, I can live without it, it's just that it kind of breaks the tests
for the recent time auditing patches [1] (I try to reset to previous
values when triggering events). I worked around it for now by
resetting the value to 1 when original value was 0... I don't know if
it can lead to some issues or not, but it would be nice if I could
reset to the actual original value...
