Buggifying critical core modules

Even in the highly unlikely scenario that function pointers someday become _smaller_ than data
pointers (which would have no benefits and which would make dynamic loading exceedingly
complicated and delicate), the vast majority of pointers are still data pointers, all of which
will have the same size.

My point is that in the real world on mainstream systems, you don't have to worry about
contingencies like the kind you mentioned anymore. Embedded, special-purpose code is
different, but then we're not talking about POSIX anymore, and lots of other assumptions go
out the window too.

I don't imagine dpkg is going to run on a microcontroller.
