So a couple of confusing bits:
1. it seems like we're losing a fair bit of the 'update out of fuckups'
situations
2. I need to test it against some of the hairball
obsoletes-as-the-result-of-an-update case.

But just from going over the code I don't see how it could be handling
those situations. Did I just miss something?

Okay - looking at it for updates case:

I did an update of libgcj

with the old depsolver it caught that libgcj-devel and gcc-java would
need to get updated as well to go with the new libgcj. the new depsolver
didn't. I think I know what's going on. on an 'update' which is both an
install and remove case it seems like we're only noticing the install
case b/c that's all txmbr has in it. We need to also store and note the
remove case so that the depsolver can traverse that path, too. Or,
alternatively, maybe we should make a third 'update or obsoletes' case
which can be traversed and allow the 'update out of pain' path that
shouldn't happen on erasures, for example.

I'll take a few whacks at the code but if you know what I'm saying or
another path, feel free to take a look.
