Yeah, I saw that, and I think I know what's causing the problem. First I 
create a bare mirror of AOSP with "repo init --mirror" and "repo sync", 
then for all my different source trees I use "repo init --reference" to 
share objects with the mirror using alternates files. Running "repo 
sync" on the bare mirror works fine. The problem occurs when I run "repo 
sync" in one of my source trees. Commits and refs have been deleted from 
the mirror, but the refs are not deleted from the repos that point to 
the mirror. So it all makes sense now. Still, I wish there were a simple 
command I could run to remove the dangling refs.
