Except that the depsolving is done by rpm libraries which are C, so invalid

Except that's not quite true either. Part of the depsolving is done with
rpmlib calls: yum loads rpm headers into a transaction and gets lists of
missing dependencies, looking for packages providing those dependencies
is done by yum itself.
In FC6 the hideous yum slowdown comes largely from reopening the rpmdb
literally hundreds of times. Check out

for some metrics. Yum 3.0.1 isn't *that* bad, but 3.0 is dog slow whereas
2.9.6 was lightning fast.
