So you want to exit a transaction in mid-swing and what? Hope that the
rpmdb is in a quasi-workable state? It's not like a db commit, we're
putting new data on disk, there's no nice and good way to just pause and
do something else.

but the rpmdb is in an inconsistent state at this point - who knows what
results we'll end up with. Not just within updating packages but also
within actually executing programs.
