I suppose it was easier to do it that way and go for reliable rather than 
efficient. After all, preupgrade is something you run at most every release, and 
stopping it in the middle is not the usual use case, so "better safe than 
sorry," it starts over.

I guess that putting time into recovery code was not efficient use of developer 
time, and as long as it produces a proper upgrade when interrupted, the unlikely 
restart case wasn't handled. As opposed to handled badly, which you really don't 
want.
