I don't think so. The cloning just failed again, much quicker:

$ time hg clone http://code.python.org/hg/branches/release2.7-maint/
destination directory: release2.7-maint
requesting all changes
adding changesets

adding file changes

Actually, I've just managed to reproduce it from dinsdale itself:

$ time hg clone http://code.python.org/hg/branches/release2.7-maint/
destination directory: release2.7-maint
requesting all changes
adding changesets
adding manifests
adding file changes
transaction abort!
rollback completed
