We know about this problem. And I think I know what is probably the best
behavior in this case - it's a matter of doing and testing it.

The gist of it is that we write a transaction journal out that records
what is not yet finished in the yum transaction. Then if we're
interrupted we can recover.

If people have code they'd like to contribute email yum-devel list.
