[Yum-devel] repomanage slowness and ts.setVSFlags

[Matthew Miller]

So, uh, I know Jeff said that this was the wrong thing to do, etc., when
this was last discussed, but the attached patch still speeds up `repomanage
-o` by order of magnitude -- from 99 seconds to 6 seconds on my x86_64 repo,
or 76 seconds to 4 on i386. I notice that createrepo does a similar thing.
