[Yum-devel] [PATCH] Add queue to presto delta rebuilds

Great, looks fine to me.  Applied and used to DL today's f17 updates.
28M total, (17 drpms, 9 rpms).

It certainly feels faster on the UI side (no blocking during DL), 
but the overall running time was about +10% (reproducible,
53s vs 58s, with less than 1s variation in multiple runs).

moreover, 
with --setopt=deltarpm=2 it's 38s vs 44s.
with --setopt=deltarpm=3 it's 32s vs 45s.

I'm not sure what is the root cause here, but noticed that
when all DLs are done and there's >1 rebuild queued,
only one rebuild process was running.
