okay did a little more digging.

when you call returnObsoletes() on a SqliteSack it does a sql call to
grab all the obsoletes at once and then it puts them into the dict it
needs as the return. Pretty straightforward.

when you call returnObsoletes() on a ListPackageSack it iterates each of
the package objects's obsoletes lists and puts them into a dict.

so we need to speed up the latter. I'm going to play as bit and see what
can be done.
