The only case in which I have experienced problems from an updated
package is with the package "helm" which is not in the Emacs core. I
could try to track down the problem and solve it within the helm
library. I'll report back here if I find anything which looks like a
core Emacs bug.

I also remember having some trouble with installing or resuming an
aborted install and getting "file exists" errors. I'd have to dig a
little to remember what exactly was happening; if I find anything I'll
start a new thread about it.

But the main point is: I think we would be well-served by pulling these
changes into 24.3 because it does not affect the user interface at all
and is therefore not going against the idea of a feature freeze, cleans
up the namespace by removing `define-package', and will make debugging
package.el for the release of 24.3 easier by using consistent variable
names and types throughout the library.
