If you tried to do it that way you'd break the system completely.  Not
all updates go through the executor.

I think it's a bad idea anyway; you'd be adding overhead to the lowest
level routines in order to support a feature that would be very seldom
used, at least in comparison to the number of times those routines are
executed.
